Which would mean that you'd need both for having such stat. Anyway, I'm
fine with putting this in 'cpu' as well, just trying to find a consensus
on what the right place is.

SCHED_DEADLINE patchset has both signaling capabilities and some
statistic reporting, bat it's a different thing.

I think schedstat could be the right place for _this_ thing here, but
since each cgroup could be throttled, we also need something which is
per-cgroup... Don't you agree?
