2012-03-14xfs: remove the per-filesystem list of dquotsChristoph Hellwig1-9/+3
Instead of keeping a separate per-filesystem list of dquots we can walk the radix tree for the two places where we need to iterate all quota structures. Reviewed-by: Dave Chinner <dchinner@redhat.com> Signed-off-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Ben Myers <bpm@sgi.com>
2012-02-29xfs: include reservations in quota reportingChristoph Hellwig1-3/+3
Report all quota usage including the currently pending reservations. This avoids the need to flush delalloc space before gathering quota information, and matches quota enforcement, which already takes the reservations into account. This fixes xfstests 270.

2012-02-29xfs: merge xfs_qm_export_dquot into xfs_qm_scall_getquotaChristoph Hellwig1-69/+49
The is no good reason to have these two separate, and for the next change we would need the full struct xfs_dquot in xfs_qm_export_dquot, so better just fold the code now instead of changing it spuriously.

2012-02-21xfs: change available ranges of softlimit and hardlimit in quota checkMitsuo Hayasaka1-2/+2
In general, quota allows us to use disk blocks and inodes up to each limit, that is, they are available if they don't exceed their limitations. Current xfs sets their available ranges to lower than them except disk inode quota check. So, this patch changes the ranges to not beyond them.

2012-01-17xfs: remove the i_size field in struct xfs_inodeChristoph Hellwig1-1/+0
There is no fundamental need to keep an in-memory inode size copy in the XFS inode. We already have the on-disk value in the dinode, and the separate in-memory copy that we need for regular files only in the XFS inode. Remove the xfs_inode i_size field and change the XFS_ISIZE macro to use the VFS inode i_size field for regular files. Switch code that was directly accessing the i_size field in the xfs_inode to XFS_ISIZE, or in cases where we are limited to regular files direct access of the VFS inode i_size field. This also allows dropping some fairly complicated code in the write path which dealt with keeping the xfs_inode i_size uptodate with the VFS i_size that is getting updated inside ->write_end. Note that we do not bother resetting the VFS i_size when truncating a file that gets freed to zero as there is no point in doing so because the VFS inode is no longer in use at this point. Just relax the assert in xfs_ifree to only check the on-disk size instead.

2012-01-13xfs: remove xfs_itruncate_dataChristoph Hellwig1-1/+8
This wrapper isn't overly useful, not to say rather confusing. Around the call to xfs_itruncate_extents it does: - add tracing - add a few asserts in debug builds - conditionally update the inode size in two places - log the inode Both the tracing and the inode logging can be moved to xfs_itruncate_extents as they are useful for the attribute fork as well - in fact the attr code already does an equivalent xfs_trans_log_inode call just after calling xfs_itruncate_extents. The conditional size updates are a mess, and there was no reason to do them in two places anyway, as the first one was conditional on the inode having extents - but without extents we xfs_itruncate_extents would be a no-op and the placement wouldn't matter anyway. Instead move the size assignments and the asserts that make sense to the callers that want it. As a side effect of this clean up xfs_setattr_size by introducing variables for the old and new inode size, and moving the size updates into a common place.

2011-10-11xfs: simplify xfs_trans_ijoin* againChristoph Hellwig1-1/+1
There is no reason to keep a reference to the inode even if we unlock it during transaction commit because we never drop a reference between the ijoin and commit. Also use this fact to merge xfs_trans_ijoin_ref back into xfs_trans_ijoin - the third argument decides if an unlock is needed now. I'm actually starting to wonder if allowing inodes to be unlocked at transaction commit really is worth the effort. The only real benefit is that they can be unlocked earlier when commiting a synchronous transactions, but that could be solved by doing the log force manually after the unlock, too.

2011-08-12xfs: remove subdirectoriesChristoph Hellwig1-0/+906
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/.
