It runs under semaphore.

Which does not matter at all, because the hole

void cleanup_module(void)
{
<an instance is cloned here>
        unregister_qdisc(&cbq_qdisc_ops);
}

remained in any case, be it under some preemptive, nonprepemtive lock or
not under a lock at all.

BTW, Rusty, a question... I do not understand, what is purpose of this "new"
module stuff at all? If we still need to query something in module.c to create
each instanse of something it smells exactly "old" broken approach. I just
do not see differences. It is not essential in this particular case,
but it would be funny to ask it each time when creating a tcp socket.
