Thanks for the per-entity tracking feature, we could know the details of each task by its help. 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!
Lei Wen (2): sched: add trace events for task and rq usage tracking sched: update cfs_rq weight earlier in enqueue_entity
