This patch add its trace support, so that we could quickly know the system status in a large time scale. The "cfs_rq->runnable_load_avg/cfs_rq->load.weight" is useful in identify load distribution status in the whole system V2: Abstract sched_cfs_rq_runnable_load and sched_cfs_rq_blocked_load using sched_cfs_rq_load_contri_template. Thanks Kamalesh for this contribution!
