The error is returned by kthread_stop(), I suspect we are running into
this:

static int kthread(void *_create)
{
        [...]
        complete(done);
        schedule();

        ret = -EINTR;

        if (!test_bit(KTHREAD_SHOULD_STOP, &self.flags)) {
                __kthread_parkme(&self);
                ret = threadfn(data);
        }
        /* we can't just return, we must preserve "self" on stack */
        do_exit(ret);
}
