net_sched: gred: red_calc_qavg() called with current qavg for backlog?

["Ward, David - 0663 - MITLL" <david.ward@ll.mit.edu>]

In net/sched/sch_gred.c:

static int gred_dump(struct Qdisc *sch, struct sk_buff *skb)
{
     struct gred_sched *table = qdisc_priv(sch);
...
     for (i = 0; i < MAX_DPs; i++) {
         struct gred_sched_data *q = table->tab[i];
         struct tc_gred_qopt opt;
...
         opt.qave = red_calc_qavg(&q->parms, &q->vars, q->vars.qavg);


I can't tell if red_calc_qavg is intentionally being passed the current 
qavg as the backlog (which effectively causes qavg to only be 
re-calculated if we are idling)?  Or should this be:

         opt.qave = red_calc_qavg(&q->parms,
                                  &q->vars,
                                  gred_backlog(table, q, sch));

Thanks,

David
