Tejun Heo 0cd9d33ace cgroup: init_tasks shouldn't be linked to the root cgroup ... 5153faac18 ("cgroup: remove cgroup_enable_task_cg_lists() optimization") removed lazy initialization of css_sets so that new tasks are always lniked to its css_set. In the process, it incorrectly ended up adding init_tasks to root css_set. They show up as PID 0's in root's cgroup.procs triggering warnings in systemd and generally confusing people. Fix it by skip css_set linking for init_tasks.
