Please have a look at the task counter subsystem: https://lwn.net/Articles/461462/

It's in the -mm tree. I'm glad to hear about another user who wants
this feature in cgroups. We need to hear about you and whether this
meets your requirements in order to get it merged upstream.

Had a quick look at your patch set. No, it does not seem to meet my
requirements. It limits the number of processes in a cgroup - that is
also very useful, but is different from my controller.

How so?
If you never move tasks to a cgroup except at setup time - which is the common case for almost everybody, I imagine, you end up achieving the same thing.
