> This patch adds a new function cgroup_unload_subsys which is to be used for
> removing a loaded subsystem during module deletion. Reference counting of the
> subsystems' modules is moved from once (at load time) to once per attached
> hierarchy (in parse_cgroupfs_options and rebind_subsystems) (i.e., 0 or 1).
> 
> It also adds a proper module_delete call in net/sched/cls_cgroup.c.
