[Cluster-devel] [PATCH v5 6/8] xfs: switch to multigrain timestamps

2023-07-13 Thread Jeff Layton
Enable multigrain timestamps, which should ensure that there is an apparent change to the timestamp whenever it has been written after being actively observed via getattr. Also, anytime the mtime changes, the ctime must also change, and those are now the only two options for xfs_trans_ichgtime.
