From: Lei Wen
Date: Mon Jul 01 2013 - 08:36:32 EST


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
