    SubjectRe: [patch] CFS scheduler, -v14

    static void distribute_fair_add(struct rq *rq, s64 delta)
    {
    struct task_struct *curr = rq->curr;
    s64 delta_fair = 0;

    if (!(sysctl_sched_load_smoothing & 32))
    return;

    if (rq->nr_running) {
    delta_fair = div64_s(delta, rq->nr_running);
    /*
    * The currently running task's next wait_runtime value does
    * not depend on the fair_clock, so fix it up explicitly:
    */
    add_wait_runtime(rq, curr, -delta_fair);
    rq->fair_clock -= delta_fair;
    }
    }

    See this line:

    delta_fair = div64_s(delta, rq->nr_running);

    Ingo, should we be replace "rq->nr_running" with "rq->raw_load_weight" here?

    Good luck
