Added support for in-kernel node monitoring ({add,remove}_node_listener()).


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@34147 a95241bf-73f2-0310-859d-f6bbb57e9c96

Implemented support for the recently introduced I/O request calls
io_request_{offset,length}(), {read_from,write_to}_io_request().


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@34137 a95241bf-73f2-0310-859d-f6bbb57e9c96

Added support for new notify_io_request() function.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@31970 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Haiku kernel interface emulation: Retrieve the capabilities for each vnode.
We do some caching using a hash table indexed by the operations vector.
* Pass the vnode capabilities to the kernel module.
* In the kernel tailor the operation vectors for volumes and vnodes passed to
the VFS according to the respective capabilities. This way those vectors look
pretty much like those from the client FS. This saves unnecessary calls when
hooks are not implemented and should also fix compatibility problems in cases
where not implementing a hook and returning an error don't mean the same to
the VFS.
* Inlined some of the kernel module Volume class getters.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@29572 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Forward the io() and cancel_io() hooks. Implemented the missing kernel
part.
* Implemented a good part of the kernel part for the support of
do_iterative_fd_io(). The forwarding of the callbacks are missing yet.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@29540 a95241bf-73f2-0310-859d-f6bbb57e9c96

* The nature of asynchronous I/O is to be asynchronous. So we can't store
an on-stack structure for the request in a hash table when forwarding the
io() hook. Create a new object (HaikuKernelIORequest) instead and store it
in a hash table in HaikuKernelFileSystem.
* Some work on the userland side of do_iterative_fd_io().
* Added some missing requests in UserlandFSUtil::is_{kernel,userland}_request().


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@29505 a95241bf-73f2-0310-859d-f6bbb57e9c96

Implemented the client side of the file cache operations.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@29401 a95241bf-73f2-0310-859d-f6bbb57e9c96

* FileSystem does now have a list of all volumes. This allows to get a volume
by ID.
* Added a three parameters version of UserlandFS::KernelEmu::publish_vnode(),
which is used by the BeOS new_vnode() emulation. It calls the new
Volume::GetVNodeType() to get the type of the node.

Theoretically BeOS FS interface style add-ons should work again, but ATM we
crash the kernel when trying to mount.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@29367 a95241bf-73f2-0310-859d-f6bbb57e9c96

Got the kernel interface compiling.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@29333 a95241bf-73f2-0310-859d-f6bbb57e9c96

Some more work towards adjusting the UserlandFS to the current FS interface:
* Split the FSCapabilities bit mask into three bit masks for the FS, the
volume, and the vnodes, since we have three independent FS interface
structures, now. The latter is not supported in the kernel add-on, yet.
* Server:
- Temporarily removed some things from the build (the BeOS interface
and the cache implementations).
- Some WIP in HaikuKernelVolume and [haiku_]kernel_emu.{h,cpp}.
- Added HaikuKernelNode, which wraps fs_vnode for the client FS.
The server is still quite a bit away from being buildable again.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@29323 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Renamed fs/vfs_select.cpp to wait_for_objects.cpp and got rid of
vfs_select.h, respectively moved most of it into the new kernel
private header wait_for_objects.h.
* Added new experimental API functions wait_for_objects[_etc](). They
work pretty much like poll(), but also for semaphores, ports, and
threads.
* Removed the "ref" parameter from notify_select_events() and the
select_sync_pool functions as well as from fd_ops::fd_[de]select(). It
is no longer needed. The FS interface select() hook still has it,
though -- the VFS will always pass 0.
* de]select_fd() take a select_info* instead of a select_sync* + ref
pair, now. Added respective functions for semaphores, ports, and
threads.



git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@22416 a95241bf-73f2-0310-859d-f6bbb57e9c96

Got rid of vnode_id and mount_id, replaced with ino_t and dev_t.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@21485 a95241bf-73f2-0310-859d-f6bbb57e9c96

Added parse_expression() to the kernel emulation.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@20436 a95241bf-73f2-0310-859d-f6bbb57e9c96

Added Haiku block cache interface to the UserlandFS server. Basically
copied and adjusted the respective kernel code.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@20367 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Added support for interfacing with Haiku style FS modules (yet
untested).
* Added library with the relevant part of the Haiku kernel interface.
The cache interface is missing, though.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@20340 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Adjusted according to the is_vnode_removed() -> get_vnode_removed()
change.
* The new notification functions are used instead of send_notification()
and notify_listener() now. Mapped them in the BeOS kernel emulation
accordingly. RamFS node monitoring seems to work now.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@20298 a95241bf-73f2-0310-859d-f6bbb57e9c96

We do now provide the BeOS style FS add-ons with the kernel interface they
need via library libuserlandfs_beos_kernel.so. Fine-tuned the legacy headers
so they can by used by the the kernel interface emulation code as well as by
the add-ons. This is actually a bit hacky, since we build everything in the
Haiku build environment and thus mix these old headers and Haiku's.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@20254 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Adjusted BeOSKernelFileSystem and BeOSKernelVolume to Haiku's FS interface.
* Moved stuff need for the BeOS interface only into the beos_* namespace.
* Shuffled a few things around to reduce the block cache implementation
dependencies. compat.h and sysdep.c are gone accordingly.
* The whole UserlandFSServer builds now and could (at least theorectically)
drive a FS add-on implementing the old interface. The required emulation of
the BeOS kernel is not yet provided, though.
