Subject: Re: [PATCH 0/4] sched: remove cpu_load decay
Date: Fri, 13 Dec 2013 21:03:03 +0100 [thread overview]
Message-ID: <20131213200303.GI2480@laptop.programming.kicks-ass.net> (raw)
In-Reply-To: <1386061556-28233-1-git-send-email-alex.shi@linaro.org>
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.
