If so, I don't mind, but why? cgroup_unload_subsys() should never be

Hmm.... I think it's generally preferable to reuse normal exit path
for error handling as much as possible.  Plus, the normal cgroup init
failure path behaves that way.  That said, it's more of a preference
and if you have technical argument, I'd be happy to give in. :)

Thanks.
