    Then its racy, unless you also changed the way your worker threads exit.

    By the time kthread_run() returns, child thread can already be gone.

    This is why I use kthread_create() : to be able to get_task_struct() so
    that task_struct cannot disappear, even if the child exits really fast :

    int worker(void *arg)
    return 0;
