 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[1].)
 
 Besides that, we have the usual miscellaneous cleanups and bug fixes.
