[PATCH] sched: fix sched_entity avg statistics update

by Vincent Guittot

With the current implementation, the load average statistics of a sched entity change according to other activity on the CPU even if this activity is done between the running window of the sched entity and have no influence on the running duration of the task. When a task wakes up on the same CPU, we currently update last_runnable_update with the return of __synchronize_entity_decay without updating the runnable_avg_sum and runnable_avg_period accordingly. In fact, we have to sync the load_contrib of the se with the rq's blocked_load_contrib before removing it from the latter (with __synchronize_entity_decay) but we must keep last_runnable_update unchanged for updating runnable_avg_sum/period during the next update_entity_load_avg.
