Merge tag 'xfs-for-linus-4.1-rc6' of git://git.kernel.org/pub/scm/linux/kernel/git/dgc/linux-xfs
Pull xfs fixes from Dave Chinner:
"This is a little larger than I'd like late in the release cycle, but
all the fixes are for regressions introduced in the 4.1-rc1 merge, or
are needed back in -stable kernels fairly quickly as they are
filesystem corruption or userspace visible correctness issues.
Changes in this update:
- regression fix for new rename whiteout code
- regression fixes for new superblock generic per-cpu counter code
- fix for incorrect error return sign introduced in 3.17
- metadata corruption fixes that need to go back to -stable kernels"
* tag 'xfs-for-linus-4.1-rc6' of git://git.kernel.org/pub/scm/linux/kernel/git/dgc/linux-xfs:
xfs: fix broken i_nlink accounting for whiteout tmpfile inode
xfs: xfs_iozero can return positive errno
xfs: xfs_attr_inactive leaves inconsistent attr fork state behind
xfs: extent size hints can round up extents past MAXEXTLEN
xfs: inode and free block counters need to use __percpu_counter_compare
percpu_counter: batch size aware __percpu_counter_compare()
xfs: use percpu_counter_read_positive for mp->m_icount
