I've no idea why any drivers do this. A tty_wakeup is very fast and it won't (when called from an IRQ) reschedule anything until the IRQ is over (in the RT kernel case it might do stuff but thats *because* it should do so).
I think just using tty_wakeup for this ought to be sufficient unless they are using the work queue for some kind of serialization of events - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
