Subject: [PATCH 08/10] ext4: switch to multigrain timestamps
Date: Wed, 26 Jun 2024 21:00:28 -0400 [thread overview]
Message-ID: <20240626-mgtime-v1-8-a189352d0f8f@kernel.org> (raw)
In-Reply-To: <20240626-mgtime-v1-0-a189352d0f8f@kernel.org>
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.
