    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"
