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"
