From 0269b585868e59b6a2ecc6ea685d39310e4fc18b Mon Sep 17 00:00:00 2001 From: Jeff Layton Date: Mon, 7 Aug 2023 15:38:43 -0400 Subject: ext4: switch to multigrain timestamps 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.
