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, like now we may get each runqueue's usage ratio by:
cfs_rq's usage ratio = cfs_rq->runnable_load_avg/cfs_rq->load.weight
Lei Wen (2): sched: add trace events for task and rq usage tracking sched: update cfs_rq weight earlier in enqueue_entity
