This controller applies a cgroup specific setting to tasks associated with an instance (similar to cpuset restricting tasks to specifics CPUs), so it is more than just identifying membership.

I looked at the commits referenced above and net/netfilter/xt_cgroup.c code in particular and I don't see how it applies to this use case. Can you elaborate?

Thanks,
