The `early_init` flags marks subsystems which may/should be initialized early. The `id` and `name` fields represents unique identifier in the array of registered subsystems for a cgroup and `name` of a subsystem respectively. The last - `root` fields represents pointer to the root of of a cgroup hierarchy.

Of course the `cgroup_subsys` structure bigger and has other fields, but it is enough for now. Now as we got to know important structures related to `cgroups` mechanism, let's return to the `cgroup_init_early` function. Main purpose of this function is to do early initialization of some subsystems. As you already may guess, these `early` subsystems should have `cgroup_subsys->early_init = 1`. Let's look what subsystems may be initialized early. Of course the `cgroup_subsys` structure is bigger and has other fields, but it is enough for now.
