Implement hot removal of spares and components. From manu@.
Implement a long desired feature of automatically incorporating a used spare into the array after a reconstruct.
Given the configuration: Components: /dev/wd0e: failed /dev/wd1e: optimal /dev/wd2e: optimal Spares: /dev/wd3e: spare
Running 'raidctl -F /dev/wd0e raid0' will now result in the following configuration after a successful rebuild: Components: /dev/wd3e: optimal /dev/wd1e: optimal /dev/wd2e: optimal No spares.
Thanks to manu@ for the development of the initial set of changes which allowed the changes to automatically incorporate a used spare to come to fruition. Thanks also to manu@ for useful discussions about and additional testing of these changes.

call buf_destroy() after buf_init(). hopefully fixes the lockdebug problem shown here:
http://mail-index.netbsd.org/tech-kern/2021/12/10/msg027851.html
but seems unlikely to fix the original problem.
tested on i386/anita. ok oster@

Extensive mechanical changes to the pools used in RAIDframe.
Alloclist remains not per-RAID, so initialize that pool separately/differently than the rest.
The remainder of pools in RF_Pools_s are now per-RAID pools. Mostly mechanical changes to functions to allocate/destroy per-RAID pools. Needed to make raidPtr available in certain cases to be able to find the per-RAID pools.
Extend rf_pool_init() to now populate a per-RAID wchan value that is unique to each pool for a given RAID device.
TODO: Complete the analysis of the minimum number of items that are required for each pool to allow IO to progress (i.e. so that a request for pool resources can always be satisfied), and dynamically scale minimum pool sizes based on RAID configuration.

getiobuf() can return NULL if there are no IO buffers available. RAIDframe can't deal with that, so create a dedicated pool of buffers to use for IO. PR_WAITOK is fine here, as we pre-allocate more than we need to guarantee IO can make progress. Tuning of pool still to come.

fix the function pointer and callback mess: - callback functions return 0 and their result is not checked; make them void. - there are two types of callbacks and they used to overload their parameters and the callback structure; separate them into "function" and "value" callbacks. - make the wait function signature consistent.

Protect calls to pool_put/pool_get that may occur in interrupt context with spl used to protect other allocations and frees, or datastructure element insertion and removal, in adjacent code.
It is almost unquestionably the case that some of the spl()/splx() calls added here are superfluous, but it really seems wrong to see:
s=splfoo(); /* frob data structure */ splx(s); pool_put(x);
and if we think we need to protect the first operation, then it is hard to see why we should not think we need to protect the next. "Better safe than sorry".
It is also almost unquestionably the case that I missed some pool gets/puts from interrupt context with my strategy for finding these calls; use of PR_NOWAIT is a strong hint that a pool may be used from interrupt context but many callers in the kernel pass a "can wait/can't wait" flag down such that my searches might not have found them. One notable area that needs to be looked at is pf.

- first kick at a major reworking of RAIDframe's memory allocation code: - all freelists converted to pools - initialization of structure members in certain cases where code was relying on specific allocation and usage properties to keep structures in a "known state" (that doesn't work with pools!). - make most pool_get() be "PR_WAITOK" until they can be analyzed further, and/or have proper error handling added. - all RF_Mallocs zero the space returned, so there is no difference between RF_Calloc and RF_Malloc. In fact, all the RF_Calloc()'s do is tend to do is get things horribly confused. Make RF_Malloc() the "general memory allocator", with RF_MallocAndAdd() the "general memory allocator with allocation list". - some of these RF_Malloc's et al. are destined to disappear. - remove rf_rdp_freelist entirely (it's not used anywhere!) - remove: #include "rf_freelist.h" - to the files that were relying on the above, add: #include "rf_general.h" - add: #include "rf_debugMem.h" to rf_shutdown.h to make it happy about the loss of: #include "rf_freelist.h".
This shrinks an i386 GENERIC kernel by approx 5K. RAIDframe now weighs in at about 162K on i386.

[Having received a definite lack of strenuous objection, a small amount of strenuous agreement, and some general agreement, this commit is going ahead because it's now starting to block some other changes I wish to make.]
Remove most of the support for the concept of "rows" from RAIDframe. While the "row" interface has been exported to the world, RAIDframe internals have really only supported a single row, even though they have feigned support of multiple rows.
Nothing changes in configuration land -- config files still need to specify a single row, etc. All auto-config structures remain fully forward/backwards compatible.
The only visible difference to the average user should be a reduction in the size of a GENERIC kernel (i386) by 4.5K. For those of us trolling through RAIDframe kernel code, a lot of the driver configuration code has become a LOT easier to read.

Everyone and their dog was using RF_ERRORMSG3 to print out the same sort of error message, over and over again, in different files. Rather than having the same text repeated in multiple .o files, create a couple of little functions to do the printing, and save a bundle of space. Also improves readability of code.

Step 2 of the disentanglement. We now look to <dev/raidframe/*> for the stuff that used to live in rf_types.h, rf_raidframe.h, rf_layout.h, rf_netbsd.h, rf_raid.h, rf_decluster,h, and a few other places. Believe it or not, when this is all done, things will be cleaner.
No functional changes to RAIDframe.

Extensive mechanical changes to the pools used in RAIDframe.
Alloclist remains not per-RAID, so initialize that pool separately/differently than the rest.
The remainder of pools in RF_Pools_s are now per-RAID pools. Mostly mechanical changes to functions to allocate/destroy per-RAID pools. Needed to make raidPtr available in certain cases to be able to find the per-RAID pools.
Extend rf_pool_init() to now populate a per-RAID wchan value that is unique to each pool for a given RAID device.
TODO: Complete the analysis of the minimum number of items that are required for each pool to allow IO to progress (i.e. so that a request for pool resources can always be satisfied), and dynamically scale minimum pool sizes based on RAID configuration.

getiobuf() can return NULL if there are no IO buffers available. RAIDframe can't deal with that, so create a dedicated pool of buffers to use for IO. PR_WAITOK is fine here, as we pre-allocate more than we need to guarantee IO can make progress. Tuning of pool still to come.

fix the function pointer and callback mess: - callback functions return 0 and their result is not checked; make them void. - there are two types of callbacks and they used to overload their parameters and the callback structure; separate them into "function" and "value" callbacks. - make the wait function signature consistent.

Protect calls to pool_put/pool_get that may occur in interrupt context with spl used to protect other allocations and frees, or datastructure element insertion and removal, in adjacent code.
It is almost unquestionably the case that some of the spl()/splx() calls added here are superfluous, but it really seems wrong to see:
s=splfoo(); /* frob data structure */ splx(s); pool_put(x);
and if we think we need to protect the first operation, then it is hard to see why we should not think we need to protect the next. "Better safe than sorry".
It is also almost unquestionably the case that I missed some pool gets/puts from interrupt context with my strategy for finding these calls; use of PR_NOWAIT is a strong hint that a pool may be used from interrupt context but many callers in the kernel pass a "can wait/can't wait" flag down such that my searches might not have found them. One notable area that needs to be looked at is pf.

_rf_create_managed_mutex() is doing just a simple:

now. The rest of the fluff is no longer needed. It also cannot fail, so error checking on rf_create_managed_mutex() is just wasting space.
Nuke the #define's associated with rf_create_managed_mutex(). Convert rf_create_managed_mutex(listp,m) to just rf_mutex_init(m). Remove wasteful "error checking" and simplify all instances where this is called. (another 0.3K saved in the binary, but the real savings is in code readability!)

- first kick at a major reworking of RAIDframe's memory allocation code: - all freelists converted to pools - initialization of structure members in certain cases where code was relying on specific allocation and usage properties to keep structures in a "known state" (that doesn't work with pools!). - make most pool_get() be "PR_WAITOK" until they can be analyzed further, and/or have proper error handling added. - all RF_Mallocs zero the space returned, so there is no difference between RF_Calloc and RF_Malloc. In fact, all the RF_Calloc()'s do is tend to do is get things horribly confused. Make RF_Malloc() the "general memory allocator", with RF_MallocAndAdd() the "general memory allocator with allocation list". - some of these RF_Malloc's et al. are destined to disappear. - remove rf_rdp_freelist entirely (it's not used anywhere!) - remove: #include "rf_freelist.h" - to the files that were relying on the above, add: #include "rf_general.h" - add: #include "rf_debugMem.h" to rf_shutdown.h to make it happy about the loss of: #include "rf_freelist.h".
This shrinks an i386 GENERIC kernel by approx 5K. RAIDframe now weighs in at about 162K on i386.

[Having received a definite lack of strenuous objection, a small amount of strenuous agreement, and some general agreement, this commit is going ahead because it's now starting to block some other changes I wish to make.]
Remove most of the support for the concept of "rows" from RAIDframe. While the "row" interface has been exported to the world, RAIDframe internals have really only supported a single row, even though they have feigned support of multiple rows.
Nothing changes in configuration land -- config files still need to specify a single row, etc. All auto-config structures remain fully forward/backwards compatible.
The only visible difference to the average user should be a reduction in the size of a GENERIC kernel (i386) by 4.5K. For those of us trolling through RAIDframe kernel code, a lot of the driver configuration code has become a LOT easier to read.

Extensive mechanical changes to the pools used in RAIDframe.
Alloclist remains not per-RAID, so initialize that pool separately/differently than the rest.
The remainder of pools in RF_Pools_s are now per-RAID pools. Mostly mechanical changes to functions to allocate/destroy per-RAID pools. Needed to make raidPtr available in certain cases to be able to find the per-RAID pools.
Extend rf_pool_init() to now populate a per-RAID wchan value that is unique to each pool for a given RAID device.
TODO: Complete the analysis of the minimum number of items that are required for each pool to allow IO to progress (i.e. so that a request for pool resources can always be satisfied), and dynamically scale minimum pool sizes based on RAID configuration.

getiobuf() can return NULL if there are no IO buffers available. RAIDframe can't deal with that, so create a dedicated pool of buffers to use for IO. PR_WAITOK is fine here, as we pre-allocate more than we need to guarantee IO can make progress. Tuning of pool still to come.

Protect calls to pool_put/pool_get that may occur in interrupt context with spl used to protect other allocations and frees, or datastructure element insertion and removal, in adjacent code.
It is almost unquestionably the case that some of the spl()/splx() calls added here are superfluous, but it really seems wrong to see:
s=splfoo(); /* frob data structure */ splx(s); pool_put(x);
and if we think we need to protect the first operation, then it is hard to see why we should not think we need to protect the next. "Better safe than sorry".
It is also almost unquestionably the case that I missed some pool gets/puts from interrupt context with my strategy for finding these calls; use of PR_NOWAIT is a strong hint that a pool may be used from interrupt context but many callers in the kernel pass a "can wait/can't wait" flag down such that my searches might not have found them. One notable area that needs to be looked at is pf.

_rf_create_managed_mutex() is doing just a simple:

- first kick at a major reworking of RAIDframe's memory allocation code: - all freelists converted to pools - initialization of structure members in certain cases where code was relying on specific allocation and usage properties to keep structures in a "known state" (that doesn't work with pools!). - make most pool_get() be "PR_WAITOK" until they can be analyzed further, and/or have proper error handling added. - all RF_Mallocs zero the space returned, so there is no difference between RF_Calloc and RF_Malloc. In fact, all the RF_Calloc()'s do is tend to do is get things horribly confused. Make RF_Malloc() the "general memory allocator", with RF_MallocAndAdd() the "general memory allocator with allocation list". - some of these RF_Malloc's et al. are destined to disappear. - remove rf_rdp_freelist entirely (it's not used anywhere!) - remove: #include "rf_freelist.h" - to the files that were relying on the above, add: #include "rf_general.h" - add: #include "rf_debugMem.h" to rf_shutdown.h to make it happy about the loss of: #include "rf_freelist.h".
This shrinks an i386 GENERIC kernel by approx 5K. RAIDframe now weighs in at about 162K on i386.

[Having received a definite lack of strenuous objection, a small amount of strenuous agreement, and some general agreement, this commit is going ahead because it's now starting to block some other changes I wish to make.]
Remove most of the support for the concept of "rows" from RAIDframe. While the "row" interface has been exported to the world, RAIDframe internals have really only supported a single row, even though they have feigned support of multiple rows.
Nothing changes in configuration land -- config files still need to specify a single row, etc. All auto-config structures remain fully forward/backwards compatible.
The only visible difference to the average user should be a reduction in the size of a GENERIC kernel (i386) by 4.5K. For those of us trolling through RAIDframe kernel code, a lot of the driver configuration code has become a LOT easier to read.

Extensive mechanical changes to the pools used in RAIDframe.
Alloclist remains not per-RAID, so initialize that pool separately/differently than the rest.
The remainder of pools in RF_Pools_s are now per-RAID pools. Mostly mechanical changes to functions to allocate/destroy per-RAID pools. Needed to make raidPtr available in certain cases to be able to find the per-RAID pools.
Extend rf_pool_init() to now populate a per-RAID wchan value that is unique to each pool for a given RAID device.
TODO: Complete the analysis of the minimum number of items that are required for each pool to allow IO to progress (i.e. so that a request for pool resources can always be satisfied), and dynamically scale minimum pool sizes based on RAID configuration.

getiobuf() can return NULL if there are no IO buffers available. RAIDframe can't deal with that, so create a dedicated pool of buffers to use for IO. PR_WAITOK is fine here, as we pre-allocate more than we need to guarantee IO can make progress. Tuning of pool still to come.

Protect calls to pool_put/pool_get that may occur in interrupt context with spl used to protect other allocations and frees, or datastructure element insertion and removal, in adjacent code.
It is almost unquestionably the case that some of the spl()/splx() calls added here are superfluous, but it really seems wrong to see:
s=splfoo(); /* frob data structure */ splx(s); pool_put(x);
and if we think we need to protect the first operation, then it is hard to see why we should not think we need to protect the next. "Better safe than sorry".
It is also almost unquestionably the case that I missed some pool gets/puts from interrupt context with my strategy for finding these calls; use of PR_NOWAIT is a strong hint that a pool may be used from interrupt context but many callers in the kernel pass a "can wait/can't wait" flag down such that my searches might not have found them. One notable area that needs to be looked at is pf.

- first kick at a major reworking of RAIDframe's memory allocation code: - all freelists converted to pools - initialization of structure members in certain cases where code was relying on specific allocation and usage properties to keep structures in a "known state" (that doesn't work with pools!). - make most pool_get() be "PR_WAITOK" until they can be analyzed further, and/or have proper error handling added. - all RF_Mallocs zero the space returned, so there is no difference between RF_Calloc and RF_Malloc. In fact, all the RF_Calloc()'s do is tend to do is get things horribly confused. Make RF_Malloc() the "general memory allocator", with RF_MallocAndAdd() the "general memory allocator with allocation list". - some of these RF_Malloc's et al. are destined to disappear. - remove rf_rdp_freelist entirely (it's not used anywhere!) - remove: #include "rf_freelist.h" - to the files that were relying on the above, add: #include "rf_general.h" - add: #include "rf_debugMem.h" to rf_shutdown.h to make it happy about the loss of: #include "rf_freelist.h".
This shrinks an i386 GENERIC kernel by approx 5K. RAIDframe now weighs in at about 162K on i386.

[Having received a definite lack of strenuous objection, a small amount of strenuous agreement, and some general agreement, this commit is going ahead because it's now starting to block some other changes I wish to make.]
Remove most of the support for the concept of "rows" from RAIDframe. While the "row" interface has been exported to the world, RAIDframe internals have really only supported a single row, even though they have feigned support of multiple rows.
Nothing changes in configuration land -- config files still need to specify a single row, etc. All auto-config structures remain fully forward/backwards compatible.
The only visible difference to the average user should be a reduction in the size of a GENERIC kernel (i386) by 4.5K. For those of us trolling through RAIDframe kernel code, a lot of the driver configuration code has become a LOT easier to read.

Extensive mechanical changes to the pools used in RAIDframe.
Alloclist remains not per-RAID, so initialize that pool separately/differently than the rest.
The remainder of pools in RF_Pools_s are now per-RAID pools. Mostly mechanical changes to functions to allocate/destroy per-RAID pools. Needed to make raidPtr available in certain cases to be able to find the per-RAID pools.
Extend rf_pool_init() to now populate a per-RAID wchan value that is unique to each pool for a given RAID device.
TODO: Complete the analysis of the minimum number of items that are required for each pool to allow IO to progress (i.e. so that a request for pool resources can always be satisfied), and dynamically scale minimum pool sizes based on RAID configuration.

getiobuf() can return NULL if there are no IO buffers available. RAIDframe can't deal with that, so create a dedicated pool of buffers to use for IO. PR_WAITOK is fine here, as we pre-allocate more than we need to guarantee IO can make progress. Tuning of pool still to come.

- Change the allocation macros to be more like function calls - Change sizeof(type) -> sizeof(*variable) - Use macros for the long buffer length allocations - Remove "bit polishing" memsets() -- do them only once - Remove unnecessary casts
Thanks to oster@ for finding bugs and testing.

Protect calls to pool_put/pool_get that may occur in interrupt context with spl used to protect other allocations and frees, or datastructure element insertion and removal, in adjacent code.
It is almost unquestionably the case that some of the spl()/splx() calls added here are superfluous, but it really seems wrong to see:
s=splfoo(); /* frob data structure */ splx(s); pool_put(x);
and if we think we need to protect the first operation, then it is hard to see why we should not think we need to protect the next. "Better safe than sorry".
It is also almost unquestionably the case that I missed some pool gets/puts from interrupt context with my strategy for finding these calls; use of PR_NOWAIT is a strong hint that a pool may be used from interrupt context but many callers in the kernel pass a "can wait/can't wait" flag down such that my searches might not have found them. One notable area that needs to be looked at is pf.

_rf_create_managed_mutex() is doing just a simple:

Nuke the #define's associated with rf_create_managed_mutex(). Convert rf_create_managed_mutex(listp,m) to just rf_mutex_init(m). Remove wasteful "error checking" and simplify all instances where this is called. (another 0.3K saved in the binary, but the real savings is in code readability!)

- first kick at a major reworking of RAIDframe's memory allocation code: - all freelists converted to pools - initialization of structure members in certain cases where code was relying on specific allocation and usage properties to keep structures in a "known state" (that doesn't work with pools!). - make most pool_get() be "PR_WAITOK" until they can be analyzed further, and/or have proper error handling added. - all RF_Mallocs zero the space returned, so there is no difference between RF_Calloc and RF_Malloc. In fact, all the RF_Calloc()'s do is tend to do is get things horribly confused. Make RF_Malloc() the "general memory allocator", with RF_MallocAndAdd() the "general memory allocator with allocation list". - some of these RF_Malloc's et al. are destined to disappear. - remove rf_rdp_freelist entirely (it's not used anywhere!) - remove: #include "rf_freelist.h" - to the files that were relying on the above, add: #include "rf_general.h" - add: #include "rf_debugMem.h" to rf_shutdown.h to make it happy about the loss of: #include "rf_freelist.h".
This shrinks an i386 GENERIC kernel by approx 5K. RAIDframe now weighs in at about 162K on i386.

[Having received a definite lack of strenuous objection, a small amount of strenuous agreement, and some general agreement, this commit is going ahead because it's now starting to block some other changes I wish to make.]
Remove most of the support for the concept of "rows" from RAIDframe. While the "row" interface has been exported to the world, RAIDframe internals have really only supported a single row, even though they have feigned support of multiple rows.
Nothing changes in configuration land -- config files still need to specify a single row, etc. All auto-config structures remain fully forward/backwards compatible.
The only visible difference to the average user should be a reduction in the size of a GENERIC kernel (i386) by 4.5K. For those of us trolling through RAIDframe kernel code, a lot of the driver configuration code has become a LOT easier to read.

Step 2 of the disentanglement. We now look to <dev/raidframe/*> for the stuff that used to live in rf_types.h, rf_raidframe.h, rf_layout.h, rf_netbsd.h, rf_raid.h, rf_decluster,h, and a few other places. Believe it or not, when this is all done, things will be cleaner.

fix the function pointer and callback mess: - callback functions return 0 and their result is not checked; make them void. - there are two types of callbacks and they used to overload their parameters and the callback structure; separate them into "function" and "value" callbacks. - make the wait function signature consistent.

Protect calls to pool_put/pool_get that may occur in interrupt context with spl used to protect other allocations and frees, or datastructure element insertion and removal, in adjacent code.
It is almost unquestionably the case that some of the spl()/splx() calls added here are superfluous, but it really seems wrong to see:
s=splfoo(); /* frob data structure */ splx(s); pool_put(x);
and if we think we need to protect the first operation, then it is hard to see why we should not think we need to protect the next. "Better safe than sorry".
It is also almost unquestionably the case that I missed some pool gets/puts from interrupt context with my strategy for finding these calls; use of PR_NOWAIT is a strong hint that a pool may be used from interrupt context but many callers in the kernel pass a "can wait/can't wait" flag down such that my searches might not have found them. One notable area that needs to be looked at is pf.

- first kick at a major reworking of RAIDframe's memory allocation code: - all freelists converted to pools - initialization of structure members in certain cases where code was relying on specific allocation and usage properties to keep structures in a "known state" (that doesn't work with pools!). - make most pool_get() be "PR_WAITOK" until they can be analyzed further, and/or have proper error handling added. - all RF_Mallocs zero the space returned, so there is no difference between RF_Calloc and RF_Malloc. In fact, all the RF_Calloc()'s do is tend to do is get things horribly confused. Make RF_Malloc() the "general memory allocator", with RF_MallocAndAdd() the "general memory allocator with allocation list". - some of these RF_Malloc's et al. are destined to disappear. - remove rf_rdp_freelist entirely (it's not used anywhere!) - remove: #include "rf_freelist.h" - to the files that were relying on the above, add: #include "rf_general.h" - add: #include "rf_debugMem.h" to rf_shutdown.h to make it happy about the loss of: #include "rf_freelist.h".
This shrinks an i386 GENERIC kernel by approx 5K. RAIDframe now weighs in at about 162K on i386.

[Having received a definite lack of strenuous objection, a small amount of strenuous agreement, and some general agreement, this commit is going ahead because it's now starting to block some other changes I wish to make.]
Remove most of the support for the concept of "rows" from RAIDframe. While the "row" interface has been exported to the world, RAIDframe internals have really only supported a single row, even though they have feigned support of multiple rows.
Nothing changes in configuration land -- config files still need to specify a single row, etc. All auto-config structures remain fully forward/backwards compatible.
The only visible difference to the average user should be a reduction in the size of a GENERIC kernel (i386) by 4.5K. For those of us trolling through RAIDframe kernel code, a lot of the driver configuration code has become a LOT easier to read.

Step 2 of the disentanglement. We now look to <dev/raidframe/*> for the stuff that used to live in rf_types.h, rf_raidframe.h, rf_layout.h, rf_netbsd.h, rf_raid.h, rf_decluster,h, and a few other places. Believe it or not, when this is all done, things will be cleaner.
No functional changes to RAIDframe.

Get recent changes into the tree: - make component_label variables more consistent (==> clabel) - re-work incorrect component configuration code - re-work disk configuration code - cleanup initial configuration of raidPtr info - add auto-detection of components and RAID sets (Disabled, for now) - allow / on RAID sets (Disabled, for now) - rename "config_disk_queue" to "rf_ConfigureDiskQueue" and properly prototype in rf_diskqueue.h - protect some headers with #if _KERNEL (XXX this needs to be fixed properly) and cleanup header formatting. - expand the component labels (yes, they should be backward/forward compatible) - other bits and pieces (some function names are still bogus, and will get changed soon)

fix the function pointer and callback mess: - callback functions return 0 and their result is not checked; make them void. - there are two types of callbacks and they used to overload their parameters and the callback structure; separate them into "function" and "value" callbacks. - make the wait function signature consistent.

Protect calls to pool_put/pool_get that may occur in interrupt context with spl used to protect other allocations and frees, or datastructure element insertion and removal, in adjacent code.
It is almost unquestionably the case that some of the spl()/splx() calls added here are superfluous, but it really seems wrong to see:
s=splfoo(); /* frob data structure */ splx(s); pool_put(x);
and if we think we need to protect the first operation, then it is hard to see why we should not think we need to protect the next. "Better safe than sorry".
It is also almost unquestionably the case that I missed some pool gets/puts from interrupt context with my strategy for finding these calls; use of PR_NOWAIT is a strong hint that a pool may be used from interrupt context but many callers in the kernel pass a "can wait/can't wait" flag down such that my searches might not have found them. One notable area that needs to be looked at is pf.

- first kick at a major reworking of RAIDframe's memory allocation code: - all freelists converted to pools - initialization of structure members in certain cases where code was relying on specific allocation and usage properties to keep structures in a "known state" (that doesn't work with pools!). - make most pool_get() be "PR_WAITOK" until they can be analyzed further, and/or have proper error handling added. - all RF_Mallocs zero the space returned, so there is no difference between RF_Calloc and RF_Malloc. In fact, all the RF_Calloc()'s do is tend to do is get things horribly confused. Make RF_Malloc() the "general memory allocator", with RF_MallocAndAdd() the "general memory allocator with allocation list". - some of these RF_Malloc's et al. are destined to disappear. - remove rf_rdp_freelist entirely (it's not used anywhere!) - remove: #include "rf_freelist.h" - to the files that were relying on the above, add: #include "rf_general.h" - add: #include "rf_debugMem.h" to rf_shutdown.h to make it happy about the loss of: #include "rf_freelist.h".
This shrinks an i386 GENERIC kernel by approx 5K. RAIDframe now weighs in at about 162K on i386.

[Having received a definite lack of strenuous objection, a small amount of strenuous agreement, and some general agreement, this commit is going ahead because it's now starting to block some other changes I wish to make.]
Remove most of the support for the concept of "rows" from RAIDframe. While the "row" interface has been exported to the world, RAIDframe internals have really only supported a single row, even though they have feigned support of multiple rows.
Nothing changes in configuration land -- config files still need to specify a single row, etc. All auto-config structures remain fully forward/backwards compatible.
The only visible difference to the average user should be a reduction in the size of a GENERIC kernel (i386) by 4.5K. For those of us trolling through RAIDframe kernel code, a lot of the driver configuration code has become a LOT easier to read.

Everyone and their dog was using RF_ERRORMSG3 to print out the same sort of error message, over and over again, in different files. Rather than having the same text repeated in multiple .o files, create a couple of little functions to do the printing, and save a bundle of space. Also improves readability of code.

Protect calls to pool_put/pool_get that may occur in interrupt context with spl used to protect other allocations and frees, or datastructure element insertion and removal, in adjacent code.
It is almost unquestionably the case that some of the spl()/splx() calls added here are superfluous, but it really seems wrong to see:
s=splfoo(); /* frob data structure */ splx(s); pool_put(x);
and if we think we need to protect the first operation, then it is hard to see why we should not think we need to protect the next. "Better safe than sorry".
It is also almost unquestionably the case that I missed some pool gets/puts from interrupt context with my strategy for finding these calls; use of PR_NOWAIT is a strong hint that a pool may be used from interrupt context but many callers in the kernel pass a "can wait/can't wait" flag down such that my searches might not have found them. One notable area that needs to be looked at is pf.

Adjust _rf_ShutdownCreate() so that it is willing to wait for more memory. Since we only now ever "return(0)", just return (void) instead.
Cleanup all uses of rf_ShutdownCreate() to not worry about it ever failing. Shaves another 600 bytes off of an i386 GENERIC kernel.

Nuke a bunch of unused variables: - node_queue_cond - quiescent_cond - eq_cond - desc->cond - desc->head - diskqueue->numWaiting
Nuke rf_print_unable_to_init_cond(). Nuke rf_TerminateDiskQueues prototype from rf_diskqueue.h.

init_dqd and clean_dqd don't do enough to be their own functions, and just serve to cause confusion. Back-merge their contents to their (only) calling spots and nuke them.

Some days you wonder if some of the function declaration consistency was just an accident in the first place. Cleanup function decls and a few comments. [ok.. so I wasn't going to fix this many.. but once you're on a roll....]

_rf_create_managed_cond() is now left doing nothing. Convert callers. Mash DO_RAID_COND in rf_driver.c out of existance.
- Nuke (already #if 0'ed) _rf_create_managed_lkmgr_mutex() while we're busy here.
simplify DO_INIT in rf_engine.c

_rf_create_managed_mutex() is doing just a simple:
rf_mutex_init(m)
now. The rest of the fluff is no longer needed. It also cannot fail, so error checking on rf_create_managed_mutex() is just wasting space.
Nuke the #define's associated with rf_create_managed_mutex(). Convert rf_create_managed_mutex(listp,m) to just rf_mutex_init(m). Remove wasteful "error checking" and simplify all instances where this is called. (another 0.3K saved in the binary, but the real savings is in code readability!)

- first kick at a major reworking of RAIDframe's memory allocation code: - all freelists converted to pools - initialization of structure members in certain cases where code was relying on specific allocation and usage properties to keep structures in a "known state" (that doesn't work with pools!). - make most pool_get() be "PR_WAITOK" until they can be analyzed further, and/or have proper error handling added. - all RF_Mallocs zero the space returned, so there is no difference between RF_Calloc and RF_Malloc. In fact, all the RF_Calloc()'s do is tend to do is get things horribly confused. Make RF_Malloc() the "general memory allocator", with RF_MallocAndAdd() the "general memory allocator with allocation list". - some of these RF_Malloc's et al. are destined to disappear. - remove rf_rdp_freelist entirely (it's not used anywhere!) - remove: #include "rf_freelist.h" - to the files that were relying on the above, add: #include "rf_general.h" - add: #include "rf_debugMem.h" to rf_shutdown.h to make it happy about the loss of: #include "rf_freelist.h".
This shrinks an i386 GENERIC kernel by approx 5K. RAIDframe now weighs in at about 162K on i386.

[Having received a definite lack of strenuous objection, a small amount of strenuous agreement, and some general agreement, this commit is going ahead because it's now starting to block some other changes I wish to make.]
Remove most of the support for the concept of "rows" from RAIDframe. While the "row" interface has been exported to the world, RAIDframe internals have really only supported a single row, even though they have feigned support of multiple rows.
Nothing changes in configuration land -- config files still need to specify a single row, etc. All auto-config structures remain fully forward/backwards compatible.
The only visible difference to the average user should be a reduction in the size of a GENERIC kernel (i386) by 4.5K. For those of us trolling through RAIDframe kernel code, a lot of the driver configuration code has become a LOT easier to read.

Everyone and their dog was using RF_ERRORMSG3 to print out the same sort of error message, over and over again, in different files. Rather than having the same text repeated in multiple .o files, create a couple of little functions to do the printing, and save a bundle of space. Also improves readability of code.

Step 2 of the disentanglement. We now look to <dev/raidframe/*> for the stuff that used to live in rf_types.h, rf_raidframe.h, rf_layout.h, rf_netbsd.h, rf_raid.h, rf_decluster,h, and a few other places. Believe it or not, when this is all done, things will be cleaner.
No functional changes to RAIDframe.

Get recent changes into the tree: - make component_label variables more consistent (==> clabel) - re-work incorrect component configuration code - re-work disk configuration code - cleanup initial configuration of raidPtr info - add auto-detection of components and RAID sets (Disabled, for now) - allow / on RAID sets (Disabled, for now) - rename "config_disk_queue" to "rf_ConfigureDiskQueue" and properly prototype in rf_diskqueue.h - protect some headers with #if _KERNEL (XXX this needs to be fixed properly) and cleanup header formatting. - expand the component labels (yes, they should be backward/forward compatible) - other bits and pieces (some function names are still bogus, and will get changed soon)
