* Got rid of the duplicated functionalities provided by RWLocker.cpp, and
Locker.cpp.
* The services are now using recursive_locks, and rw_locks instead.

Patch by Bryce Groff, some changes by myself:
* devfs:
- devfs_[un]publish_partition(): They no longer get the partition path as
parameter, but rather the device path and the partition name.
- Added devfs_rename_partition(), which renames an already published
partition node.
* KPartition/KDiskDevice:
- Replaced the fPublished flag by fPublishedName, the name under which the
partition is published. This simplifies UnpublishDevice() and makes it
practically infallible.
- Added GetFileName(), which only returns the partition's file name.
Simplified GetPath() by using it.
- When a partition is added/removed the subsequent sibling partitions get a
new index. Now we also rename their published device nodes (and those of
their descendents). When something goes wrong we unpublish the concerned
partition's device to be on the safe side. Would be a shame to accidentally
format the wrong partition, eh? :-)

On a media change, the KDiskDevice must do a bit more than it did:
* it now updates the partition data,
* the flags,
* and the disk geometry - and that now allows the session add-on to actually
detect a newly inserted CD.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@22918 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Added an UninitializeMedia() method to KDiskDevice that also resets the
device geometry.
* If SetTo() reports no media, and GetGeometry() fails, the device geometry
is now reset as well.
* KDiskDeviceManager::_ScanPartition() no longer unmarks the partition busy;
this is now done by the caller, and done independently from the outcome of
_ScanPartition(). This also fixes the problem that devices with no media
were never marked unbusy (and thus were ignored subsequently).


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@22912 a95241bf-73f2-0310-859d-f6bbb57e9c96

Folded KPhysicalPartition into KPartition. Removed the notion of shadow
partitions from the disk device manager.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@22800 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Fixed a possible dead lock between the kernel daemon and the DDM; the media
status checker now only tries to lock the manager, it won't wait anymore.
* Added MediaChanged() and UpdateMediaStatusIfNeeded() methods to KDiskDevice.
* KDiskDeviceManager::_CheckMediaStatus() now uses these new methods; it should
no longer detect removed media more than once :-)

The disk device manager now periodically checks for media changes - all it does
is dump its findings, but it's an (untested) start.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@22598 a95241bf-73f2-0310-859d-f6bbb57e9c96

Make the compiler happy. Shadowing super class methods with different signature is a very annoying C++ feature.


git-svn-id: file:///srv/svn/repos/haiku/trunk/current@11069 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Changes to use KPath where possible now.
* Made GetMediaStatus() a bit more robust. If the ioctl fails (e.g. if it
is not implemented as in Thomas' drivers), it gets the device geometry
and does not fail, if the device is not removable.


git-svn-id: file:///srv/svn/repos/haiku/trunk/current@9546 a95241bf-73f2-0310-859d-f6bbb57e9c96

Shadow partition related changes:
* Fixed handling of the deletion (removal) of shadow partitions. Formerly
the shadow partition corresponding to the disk device wasn't removed
properly.
* Added a shadow_id field to the user_partition_data structure which
contains the ID of the shadow partition, if it is one. The id field
will hold the ID of the physical partition.


git-svn-id: file:///srv/svn/repos/haiku/trunk/current@3974 a95241bf-73f2-0310-859d-f6bbb57e9c96

Fixed handling of partition and device flags and statuses.


git-svn-id: file:///srv/svn/repos/haiku/trunk/current@3898 a95241bf-73f2-0310-859d-f6bbb57e9c96

* More shadow partition support.
* Writing disk device/partition data into userland buffer added.
* Migration of some definitions into <DiskDeviceDefs.h> header.
* Small bug fixes.


git-svn-id: file:///srv/svn/repos/haiku/trunk/current@3882 a95241bf-73f2-0310-859d-f6bbb57e9c96

Made KPartition abstract and derived two classes, KPhysicalPartition
and KShadowPartition from it. KPhysicalPartition represents a partition
that exists on-disk, while KShadowPartition is a partition edited by the
API user, but not yet written to disk. Related changes in other classes.


git-svn-id: file:///srv/svn/repos/haiku/trunk/current@3851 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Implemented what was left to do for KDiskDevice and KPartition
management regarding removal and deletion of objects.
* Fixed the file disk system related stuff. KFileDiskSystem now uses the
virtualdrive driver. The former method was seemed simple and brilliant,
but the B_SET_PARTITION ioctl wouldn't work.


git-svn-id: file:///srv/svn/repos/haiku/trunk/current@3650 a95241bf-73f2-0310-859d-f6bbb57e9c96

Some small adjustments for KFileDiskDevice. Added Dump().


git-svn-id: file:///srv/svn/repos/haiku/trunk/current@3600 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Made {Publish,Unpublish}Device() virtual and implemented them in
KPartition and as no-ops in KDiskDevice.
* Prefixed partition names with "obos_" to not interfere with R5's
partition names.


git-svn-id: file:///srv/svn/repos/haiku/trunk/current@3509 a95241bf-73f2-0310-859d-f6bbb57e9c96

Implemented a preliminary disk device scanning in KDiskDeviceManager.
Some changes to KPartition, KDiskDevice, KDiskSystem on this way.
Still missing is KPartition::Publish() and its invocation in
KDiskDeviceManager. Then everything should be in place to start with
porting the scanning parts of our disk system modules.


git-svn-id: file:///srv/svn/repos/haiku/trunk/current@3486 a95241bf-73f2-0310-859d-f6bbb57e9c96
