Does it make autofs easier if d_op->d_automount() is allowed to return -EXDEV
to request this? Then you can return it in Oz mode to allow the daemon to
see/use the underlying mountpoint without recursing back into d_automount().
Ideally, the daemon would use AT_NO_AUTOMOUNT, but there's no way to pass that
to sys_mount() or sys_umount().
