The main difference is that this version doesn't add a new callback for an association change during a fork -- it lets subsystems handle such cases by themselves by allowing for a private pointer to be passed around between the callbacks. * Pass a cgroup_fork_state structure between the cgroup_{can,cancel,post}_fork hooks which stores the private opaque pointer for each subsystem. This allows for subsystems to decide which (if any) state to save in the can_fork callback to refer back to in the post_fork callback.
