    The device is supposed to know what it's doing. Sure it defeats the
    elevators work a bit, but again the driver should know best. Besides, it
    doesn't seem worthwhile to go to any lengths detecting this.

    But in general I agree, device request_fn should never touch a plugged
    queue.
