Merge tag 'xfs-for-linus-4.4' of git://git.kernel.org/pub/scm/linux/kernel/git/dgc/linux-xfs
Pull xfs updates from Dave Chinner:
"There is nothing really major here - the only significant addition is
the per-mount operation statistics infrastructure. Otherwises there's
various ACL, xattr, DAX, AIO and logging fixes, and a smattering of
small cleanups and fixes elsewhere.
Summary:
- per-mount operational statistics in sysfs
- fixes for concurrent aio append write submission
- various logging fixes
- detection of zeroed logs and invalid log sequence numbers on v5 filesystems
- memory allocation failure message improvements
- a bunch of xattr/ACL fixes
- fdatasync optimisation
- miscellaneous other fixes and cleanups"
