Again... sorry, I don't try to be picky, just want to know if its worth or
not...
Would not be better something like:
if (idle == NOT_IDLE || rq->nr_running > 1) {
if (rq->nr_running)
source_load = (source_load*rq->prio_bias) / rq->nr_running;
}
wrt the integer math ? Think of
100*( 5/5) vs 500/5
100*( 6/5) vs 600/5
100*( 7/5) vs 700/5
100*( 8/5) vs 800/5
100*( 9/5) vs 900/5
100*(10/5) vs 1000/5
