Yes, the functions you patched would only be called from subsystems or there should be no way to obtain a struct cgroup_subsys reference anyway (hence it's ok to always branch as if ss==NULL).
I'd prefer a variant that wouldn't compile the affected codepaths when there are no subsystems registered, however, I couldn't come up with a way how to do it without some preprocessor ugliness.
