If you want a state machine, code it to make state transitions based on events, not history. "If I came from <here>" is a notoriously error prone software structure, closely affiliated with spaghetti code (and meatball programmers. (Plus of course garlic bread and cheap red wine.) Maybe you're not sufficiently de-coupling some state machine from a specific driver. Events are only supposed to cause state transitions, and the drivers are allowed to care about, and expose, such states ... they should largely ignore events, except maybe to issue them, in favor of states. -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
