Merge tag 'xfs-for-linus-4.10-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/dgc/linux-xfs
Pull xfs updates from Dave Chinner: "There is quite a varied bunch of stuff in this update, and some of it you will have already merged through the ext4 tree which imported the dax-4.10-iomap-pmd topic branch from the XFS tree. There is also a new direct IO implementation that uses the iomap infrastructure. It's much simpler, faster, and has lower IO latency than the existing direct IO infrastructure. Summary: - DAX PMD faults via iomap infrastructure - Direct-io support in iomap infrastructure - removal of now-redundant XFS inode iolock, replaced with VFS i_rwsem - synchronisation with fixes and changes in userspace libxfs code - extent tree lookup helpers - lots of little corruption detection improvements to verifiers - optimised CRC calculations - faster buffer cache lookups - deprecation of barrier/nobarrier mount options - we always use REQ_FUA/REQ_FLUSH where appropriate for data integrity now - cleanups to speculative preallocation - miscellaneous minor bug fixes and cleanups" * tag 'xfs-for-linus-4.10-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/dgc/linux-xfs: (63 commits) xfs: nuke unused tracepoint definitions xfs: use GPF_NOFS when allocating btree cursors xfs: use xfs_vn_setattr_size to check on new size xfs: deprecate barrier/nobarrier mount option xfs: Always flush caches when integrity is required xfs: ignore leaf attr ichdr.count in verifier during log replay xfs: use rhashtable to track buffer cache xfs: optimise CRC updates xfs: make xfs btree stats less huge xfs: don't cap maximum dedupe request length xfs: don't allow di_size with high bit set xfs: error out if trying to add attrs and anextents > 0 xfs: don't crash if reading a directory results in an unexpected hole xfs: complain if we don't get nextents bmap records xfs: check for bogus values in btree block headers xfs: forbid AG btrees with level == 0 xfs: several xattr functions can be void xfs: handle cow fork in xfs_bmap_trace_exlist xfs: pass state not whichfork to trace_xfs_extlist xfs: Move AGI buffer type setting to xfs_read_agi ...
