Subject: [PATCH v3 0/2] fix s_uuid and f_fsid consistency for cloned filesystems
Date: Mon, 27 Apr 2026 18:18:02 +0800 [thread overview]
Message-ID: <cover.1777281686.git.asj@kernel.org> (raw)
v3:
Thanks for the input. The plan to implement a consistent f_fsid across
all major filesystems has been dropped for now, so ext4 patch is removed.
Please refer to the discussion here [1]:

This patch set specifically addresses the issue reported by OverlayFS [2]
regarding cloned Btrfs filesystems.

btrfs: use on-disk uuid for s_uuid in temp_fsid mounts
btrfs: derive f_fsid from on-disk fsuuid and dev_t
