static inline void sfq_link(struct sfq_sched_data *q, sfq_index x)
{
	sfq_index p, n;
	int d = q->qs[x].qlen + SFQ_DEPTH;
-------------------->^^^^^^^^

	p = d;
	n = q->dep[d].next;
...

So it's really by design! (I don't know why I missed this, and why
it didn't break my lame test...)

Thanks again for stopping this disaster,
