We are going to use runnable_avg_sum and runnable_avg_period in order to get the utilization of the CPU. This statistic includes all tasks that run the CPU and not only CFS tasks.
But this rq->avg is not the one that is migration aware, right? So why use this?
We already compensate cpu_capacity for !fair tasks, so I don't see why we can't use the migration aware one (and kill this one as Yuyang keeps proposing) and compensate with the capacity factor.
