Commit24bd69cb("Btrfs: sysfs: add support to add parent for fsid") added parent argument in preparation to show the seed fsid under the sprout fsid as in the patch [1] in the mailing list. [1] Btrfs: sysfs: support seed devices in the sysfs layout But later this idea was superseded by another idea to rename the fsid as in the commitf93c39970b("btrfs: factor out sysfs code for updating sprout fsid"). So we don't need parent argument anymore. Signed-off-by: Anand Jain <anand.jain@oracle.com> Reviewed-by: David Sterba <dsterba@suse.com> Signed-off-by: David Sterba <dsterba@suse.com>
