Well, I'm not sure if I understand exactly what you are asking, but witness
only does lock order checks when you first acquire the lock. Any recursive
locks will skip the order checking altogether since recursive acquires can
never block. Similarly, trylock operations also stick order checks
altogether since they can never block either.
