Merge tag 'xfs-for-linus-4.5-2' of git://git.kernel.org/pub/scm/linux/kernel/git/dgc/linux-xfs
Pull more xfs updates from Dave Chinner:
"This is the second update for XFS that I mentioned in the original
pull request last week.
It contains a revert for a suspend regression in 4.4 and a fix for a
long standing log recovery issue that has been further exposed by all
the log recovery changes made in the original 4.5 merge.
There is one more thing in this pull request - one that I forgot to
merge into the origin. That is, pulling the XFS_IOC_FS[GS]ETXATTR
ioctl up to the VFS level so that other filesystems can also use it
for modifying project quota IDs
Summary:
- promotion of XFS_IOC_FS[GS]ETXATTR ioctl to the vfs level so that
it can be shared with other filesystems. The ext4 project quota
functionality is the first target for this. The commits in this
series have not been updated with review or final SOB tags because
the branch they were originally published in was needed by ext4.
Those tags are:
Reviewed-by: Theodore Ts'o <tytso@mit.edu>
Signed-off-by: Dave Chinner <david@fromrobit.com>
- Revert a change that is causing suspend failures.
- Fix a use-after-free that can occur on log mount failures. Been
around forever, but now exposed by other changes to log recovery
made in the first 4.5 merge"
