Patch looks good to me. 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)
