For code like this I wish C had grown named arguments for calls, just
like it has named initializers.

Something like:

	___update_load_sum(now, rq->cpu, &rq->avg_rt,
			   .load = running, .runnable = running,
			   .running = running)

would be so much easier to read... a well, maybe in another 30 years or
so.
