Subject: [PATCH v5 03/12] sched: fix avg_load computation
Date: Tue, 26 Aug 2014 13:06:46 +0200	[thread overview]
Message-ID: <1409051215-16788-4-git-send-email-vincent.guittot@linaro.org> (raw)
In-Reply-To: <1409051215-16788-1-git-send-email-vincent.guittot@linaro.org>

The computation of avg_load and avg_load_per_task should only takes into
account the number of cfs tasks. The non cfs task are already taken into
account by decreasing the cpu's capacity and they will be tracked in the
CPU's utilization (group_utilization) of the next patches
