sched: simplify bonus calculation #1
current code: delta = min(cfs_rq->sleeper_bonus, (u64)delta_exec); delta = calc_delta_mine(delta, curr->load.weight, lw); delta = min((u64)delta, cfs_rq->sleeper_bonus); drop the first min(), because we clip against sleeper_bonus in the 3rd line again. That gives: delta = calc_delta_mine(delta_exec, curr->load.weight, lw); delta = min((u64)delta, cfs_rq->sleeper_bonus); Signed-off-by: Peter Zijlstra <a.p.zijlstra@chello.nl> Signed-off-by: Ingo Molnar <mingo@elte.hu>
