Merge tag 'xfs-4.12-merge-7' of git://git.kernel.org/pub/scm/fs/xfs/xfs-linux
Pull xfs updates from Darrick Wong:
"Here are the XFS changes for 4.12. The big new feature for this
release is the new space mapping ioctl that we've been discussing
since LSF2016, but other than that most of the patches are larger bug
fixes, memory corruption prevention, and other cleanups.
Summary:
- various code cleanups
- introduce GETFSMAP ioctl
- various refactoring
- avoid dio reads past eof
- fix memory corruption and other errors with fragmented directory blocks
- fix accidental userspace memory corruptions
- publish fs uuid in superblock
- make fstrim terminatable
- fix race between quotaoff and in-core inode creation
- avoid use-after-free when finishing up w/ buffer heads
- reserve enough space to handle bmap tree resizing during cow remap"
