    Linus Torvalds authored
    Pull ext4 updates from Ted Ts'o:
     "The siginificant new ext4 feature this time around is Harshad's new
      fast_commit mode.
    
      In addition, thanks to Mauricio for fixing a race where mmap'ed pages
      that are being changed in parallel with a data=journal transaction
      commit could result in bad checksums in the failure that could cause
      journal replays to fail.
    
      Also notable is Ritesh's buffered write optimization which can result
      in significant improvements on parallel write workloads. (The kernel
      test robot reported a 330.6% improvement on fio.write_iops on a 96
      core system using DAX)
    
      Besides that, we have the usual miscellaneous cleanups and bug fixes"
