  ext4: make the updating inode data procedure atomic (2021-08-30 23:36:51 -0400)

----------------------------------------------------------------
In addition to some ext4 bug fixes and cleanups, this cycle we add the
orphan_file feature, which eliminates bottlenecks when doing a large
number of parallel truncates and file deletions, and move the discard
operation out of the jbd2 commit thread when using the discard mount
option, to better support devices with slow discard operations.
