Right, I don't think that's necessary. Stanislav, look at
nfs_callback_down:
nfs_callback_down_net(minorversion, cb_info->serv, net);
cb_info->users--;
if (cb_info->users == 0 && cb_info->task != NULL) {
kthread_stop(cb_info->task);
...
It's first destroying the service, then destroying the thread. That's
the wrong order. So we could still have the thread running svc_recv()
after the rpc service is destroyed.
