Are you referring to '[RFC PATCH 14/14] sched: implement usage tracking' https://lkml.org/lkml/2012/2/1/769 from Paul Turner? __update_entity_runnable_avg() has an additional parameter 'running' so that it can be called for a) sched_entities in update_entity_load_avg(): __update_entity_runnable_avg(..., se->on_rq, cfs_rq->curr == se)) b) rq's in update_rq_runnable_avg(): __update_entity_runnable_avg(..., runnable, runnable); I can see how it gives us two different signals for a sched_entity but for a rq?
