From d0382c698f9c9c80483987e1b4661b5d97a805d4 Mon Sep 17 00:00:00 2001 From: Jeff Layton Date: Wed, 2 Oct 2024 17:27:25 -0400 Subject: [PATCH] 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.
