Ah, I remember, cgroup_clone was a massive pain, Serge said he'd wanted to kill that, but I don't think that ever happened.
copy_process(): if (current->nsproxy != p->nsproxy) ns_cgroup_clone() cgroup_clone() mutex_lock(inode->i_mutex) mutex_lock(cgroup_mutex) cgroup_attach_task() ss->can_attach() ss->attach() [ -> cpuset_attach() ] cpuset_attach_task() set_cpus_allowed_ptr();
was the code path that made set_cpus_allowed_ptr() exclusion against fork interesting.
