libxfs: move source files

2014-06-25T04:57:53+00:00

Move all the source files that are shared with userspace into libxfs/. This is done as one big chunk simpy to get it done quickly Signed-off-by: Dave Chinner Reviewed-by: Brian Foster Signed-off-by: Dave Chinner

xfs: Nuke XFS_ERROR macro

2014-06-22T05:04:54+00:00

XFS_ERROR was designed long ago to trap return values, but it's not runtime configurable, it's not consistently used, and we can do similar error trapping with ftrace scripts and triggers from userspace. Just nuke XFS_ERROR and associated bits. Signed-off-by: Eric Sandeen Reviewed-by: Dave Chinner Signed-off-by: Dave Chinner

xfs: kill xfs_buf_geterror()

2014-06-06T06:02:12+00:00

Most of the callers are just calling ASSERT(!xfs_buf_geterror()) which means they are checking for bp->b_error == 0. If bp is null in this case, we will assert fail, and hence it's no different in result to oopsing because of a null bp. In some cases, errors have already been checked for or the function returning the buffer can't return a buffer with an error, so it's just a redundant assert. Either way, the assert can either be removed. The other two non-assert callers can just test for a buffer and error properly.

xfs: turn NLINK feature on by default

2014-05-19T21:46:40+00:00

mkfs has turned on the XFS_SB_VERSION_NLINKBIT feature bit by default since November 2007. It's about time we simply made the kernel code turn it on by default and so always convert v1 inodes to v2 inodes when reading them in from disk or allocating them. This This removes needless version checks and modification when bumping link counts on inodes, and will take code out of a few common code paths. text data bss dec hex filename 783251 100867 616 884734 d7ffe fs/xfs/xfs.o.orig 782664 100867 616 884147 d7db3 fs/xfs/xfs.o.patched Signed-off-by: Dave Chinner Reviewed-by: Christoph Hellwig Signed-off-by: Dave Chinner

xfs: update the finobt on inode free

2014-04-24T06:00:53+00:00

An inode free operation can have several effects on the finobt. If all inodes have been freed and the chunk deallocated, we remove the finobt record. If the inode chunk was previously full, we must insert a new record based on the existing inobt record. Otherwise, we modify the record in place. Create the xfs_difree_finobt() function to identify the potential scenarios and update the finobt appropriately. Signed-off-by: Brian Foster Reviewed-by: Dave Chinner Signed-off-by: Dave Chinner

xfs: refactor xfs_difree() inobt bits into xfs_difree_inobt() helper

2014-04-24T06:00:53+00:00

Refactor xfs_difree() in preparation for the finobt. xfs_difree() performs the validity checks against the ag and reads the agi header. The work of physically updating the inode allocation btree is pushed down into the new xfs_difree_inobt() helper. Signed-off-by: Brian Foster Reviewed-by: Dave Chinner Signed-off-by: Dave Chinner
