Thanks Tim. I expect this will also improve other pm-qos users, but of course they are likely not as frequently used as the idle governour. (and before anyone makes jokes about optimizing the idle loop: idle latency is very important for workloads with lots of wakeups out of idle) -Andi -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
