[PATCH v4 7/9] ext4: switch to multigrain timestamps

From: Jeff Layton <jlayton@kernel.org>
Date: 2024-07-08 15:54:03
Also in: linux-btrfs, linux-doc, linux-ext4, linux-fsdevel, linux-mm, linux-nfs, linux-xfs, lkml
Subsystem: ext4 file system, filesystems (vfs and infrastructure), the rest · Maintainers: "Theodore Ts'o", Alexander Viro, Christian Brauner, Linus Torvalds

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.

For ext4, we only need to enable the FS_MGTIME flag.
