If you have both INTERRUPTIBLE and UNINTERRUPTIBLE waiters on a list, and you were allowed to do INTERRUPTIBLE/UNINTERRUPTIBLE wakeups, the wakeup would have to do O(n) iteration to find a matching waiter. Seeing that the entire purpose of simple wait queues was to retain RT properties, that's entirely retarded ;-) -- To unsubscribe from this list: send the line "unsubscribe linux-rt-users" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
