Subject: Re: [PATCH 0/4] sched: remove cpu_load decay



I had a quick peek at the actual patches.

afaict we're now using weighted_cpuload() aka runnable_load_avg as the
->cpu_load. Whatever happened to also using the blocked_avg?

I totally hate patch 4; it seems like a random hack to make up for the
lack of blocked_avg.
