Subject: [PATCH 0/2] sched: add trace event for per-entity tracking
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
