BTW, parent is always != NULL, because the root cgroup will be
attached to the dummytop cgroup.
Hmmm? I'm confused. When ->css_online() is called for dummytop in
cgroup_init_subsys(), its parent is NULL. What am I missing?
Forget my comment, I was really confused when writing this. I was
looking only at cgroups which were created after bootup.
cheers,
