I am afraid get_fsid in s_op may conflict with "fsid=" option in /etc/exports.
Generally all FSs have UUID or device number and they can return "fsid"
correctly. But some of them may not have such id, or users may assign
different fsid for them.
Is "fsid=" value passed to superblock and can FS return it? Otherwise
they cannot implement ->get_fsid().
