    "It's a feature to add crap to drivers and subsystems that don't care!"

    That's a novel thing.

    Maybe we could add other features too. Like a "IM_NOT_AN_IDIOT" flag that
    every driver has to set in it's "struct device", so that the device
    manager knows that it wasn't written by an idiot.

    Right. That's what the IM_NOT_AN_IDIOT thing will do too - it will
    guarantee that only smart people do the right thing.

    Great idea. We'll get a better kernel in no tim!
