xfs: remove iolock lock classes
Content-Disposition: inline; filename=xfs-remove-iolock-classes Now that we never take the iolock during inode reclaim we don't need to play games with lock classes. Signed-off-by: Christoph Hellwig <hch@lst.de> Reviewed-by: Rich Johnston <rjohnston@sgi.com> Signed-off-by: Ben Myers <bpm@sgi.com>
