Hi Darrick,
Thanks for commenting..
+ memcpy(>s_uuid, fs_info->fsid, BTRFS_FSID_SIZE);
uuid_copy()?
It requires a larger migration to use uuid_t, IMO it can be done all
together, in a separate patch ?
Just for experiment, starting with struct btrfs_fs_info.fsid and
to

We didn't copy fsid to struct super_block.s_uuid so Overlay disables
index feature with btrfs as the lower FS.
