Subject: Re: [Patch] idle governor: Avoid lock acquisition to read pm_qos before entering idle
Date: Wed, 9 Feb 2011 19:46:56 -0800 [thread overview]

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)
