Ah, sorry. I'm just curious. (and I should read the code before making
quiestion.)

Assume a thread group contains threadA, threadB, threadC.

I wanted to ask "Can threadA, and threadB, and threadC
be in different cgroups ? And if so, how ns cgroup handles it ?"

Maybe I don't understand ns cgroup.

Thanks,
