I realize that in_cgroup is more consistent, but under_cgroup makes
far more sense to me. I think it's more intuitive.

So, I think in_cgroup should mean that the object is in that
particular cgroup while under_cgroup in the subhierarchy of that
cgroup.  Let's rename the other subhierarchy test to under too.  I
think that'd be a lot less confusing going forward.

Ah, I suppose the bpf part is userland visible?  If so, there isn't
much we can do and probably best to stick with in_cgroup for that
part.  Bummer but no big deal.

Thanks.
