#     Merge tag 'ext4_for_linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tytso/ext4
#     
#     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"
