This saves a divide and simplifies the code because we share it with the other /cfs_rq->load users. It also improves code size: text data bss dec hex filename 42659 2740 144 45543 b1e7 sched.o.before 42093 2740 144 44977 afb1 sched.o.after Signed-off-by: Ingo Molnar Signed-off-by: Peter Zijlstra --- diff --git a/kernel/sched_fair.c b/kernel/sched_fair.c index 31aa1b9..f2cc590 100644 --- a/kernel/sched_fair.c +++ b/kernel/sched_fair.c @@ -283,12 +283,8 @@ static u64 __sched_period(unsigned long nr_running) */ static u64 sched_slice(struct cfs_rq *cfs_rq, struct sched_entity *se) { - u64 slice = __sched_period(cfs_rq->nr_running); - - slice *= se->load.weight; - do_div(slice, cfs_rq->load.weight); - - return slice; + return calc_delta_mine(__sched_period(cfs_rq->nr_running), + se->load.weight, &cfs_rq->load); } /*
