    Merge tag 'xfs-for-linus-4.5' of git://git.kernel.org/pub/scm/linux/kernel/git/dgc/linux-xfs
    
    Pull xfs updates from Dave Chinner:
     "There's not a lot in this - the main addition is the CRC validation of
      the entire region of the log that the will be recovered, along with
      several log recovery fixes.  Most of the rest is small bug fixes and
      cleanups.
    
      I have three bug fixes still pending, all that address recently fixed
      regressions that I will send to next week after they've had some time
      in for-next.
    
      Summary:
       - extensive CRC validation during log recovery
       - several log recovery bug fixes
       - Various DAX support fixes
       - AGFL size calculation fix
       - various cleanups in preparation for new functionality
       - project quota ENOSPC notification via netlink
       - tracing and debug improvements"
