Merge tag 'xfs-for-linus-4.10-rc6-5' of git://git.kernel.org/pub/scm/fs/xfs/xfs-linux
Pull xfs uodates from Darrick Wong: "I have some more fixes this week: better input validation, corruption avoidance, build fixes, memory leak fixes, and a couple from Christoph to avoid an ENOSPC failure. Summary: - Fix race conditions in the CoW code - Fix some incorrect input validation checks - Avoid crashing fs by running out of space when freeing inodes - Fix toctou race wrt whether or not an inode has an attr - Fix build error on arm - Fix page refcount corruption when readahead fails - Don't corrupt userspace in the bmap ioctl" * tag 'xfs-for-linus-4.10-rc6-5' of git://git.kernel.org/pub/scm/fs/xfs/xfs-linux: xfs: prevent quotacheck from overloading inode lru xfs: fix bmv_count confusion w/ shared extents xfs: clear _XBF_PAGES from buffers when readahead page xfs: extsize hints are not unlikely in xfs_bmap_btalloc xfs: remove racy hasattr check from attr ops xfs: use per-AG reservations for the finobt xfs: only update mount/resv fields on success in __xfs_ag_resv_init xfs: verify dirblocklog correctly xfs: fix COW writeback race
