2011-12-16xfs: remove unused XBT_FORCE_SLEEP bitEric Sandeen
XBT_FORCE_SLEEP is no longer ever tested; it is only set and cleared. Remove it. Signed-off-by: Eric Sandeen <sandeen@sandeen.net> Reviewed-by: Dave Chinner <dchinner@redhat.com> Signed-off-by: Ben Myers <bpm@sgi.com>

2011-10-11xfs: remove xfs_buf_target_nameChristoph Hellwig
The calling convention that returns a pointer to a static buffer is fairly nasty, so just opencode it in the only caller that is left. Signed-off-by: Christoph Hellwig <hch@lst.de> Reviewed-by: Dave Chinner <dchinner@redhat.com> Signed-off-by: Alex Elder <aelder@sgi.com>
2011-10-11xfs: clean up xfs_ioerror_alertChristoph Hellwig
Instead of passing the block number and mount structure explicitly get them off the bp and fix make the argument order more natural. Also move it to xfs_buf.c and stop printing the device name given that we already get the fs name as part of xfs_alert, and we know what device is operates on because of the caller that gets printed, finally rename it to xfs_buf_ioerror_alert and pass __func__ as argument where it makes sense.

2011-10-11xfs: clean up buffer allocationChristoph Hellwig
Change _xfs_buf_initialize to allocate the buffer directly and rename it to xfs_buf_alloc now that is the only buffer allocation routine. Also remove the xfs_buf_deallocate wrapper around the kmem_zone_free calls for buffers.

2011-10-11xfs: fix buffer flushing during unmountChristoph Hellwig
The code to flush buffers in the umount code is a bit iffy: we first flush all delwri buffers out, but then might be able to queue up a new one when logging the sb counts. On a normal shutdown that one would get flushed out when doing the synchronous superblock write in xfs_unmountfs_writesb, but we skip that one if the filesystem has been shut down. Fix this by moving the delwri list flushing until just before unmounting the log, and while we're at it also remove the superflous delwri list and buffer lru flusing for the rt and log device that can never have cached or delwri buffers.

2011-10-11xfs: let xfs_bwrite callers handle the xfs_buf_relseChristoph Hellwig
Remove the xfs_buf_relse from xfs_bwrite and let the caller handle it to mirror the delwri and read paths. Also remove the mount pointer passed to xfs_bwrite, which is superflous now that we have a mount pointer in the buftarg.

2011-10-11xfs: call xfs_buf_delwri_queue directlyChristoph Hellwig
Unify the ways we add buffers to the delwri queue by always calling xfs_buf_delwri_queue directly. The xfs_bdwrite functions is removed and opencoded in its callers, and the two places setting XBF_DELWRI while a buffer is locked and expecting xfs_buf_unlock to pick it up are converted to call xfs_buf_delwri_queue directly, too. Also replace the XFS_BUF_UNDELAYWRITE macro with direct calls to xfs_buf_delwri_dequeue to make the explicit queuing/dequeuing more obvious.

2011-08-12xfs: remove subdirectoriesChristoph Hellwig
Use the move from Linux 2.6 to Linux 3.x as an excuse to kill the annoying subdirectories in the XFS source code. Besides the large amount of file rename the only changes are to the Makefile, a few files including headers with the subdirectory prefix, and the binary sysctl compat code that includes a header under fs/xfs/ from kernel/.
