    This looks good to me. Do you also need to take the semaphore in
    autofs4_catatonic_mode(), around the hijacking of the queue?

    void autofs4_catatonic_mode(struct autofs_sb_info *sbi)
    struct autofs_wait_queue *wq, *nwq;

    DPRINTK(("autofs: entering catatonic mode\n"));

    sbi->catatonic = 1;
    wq = sbi->queues;
    sbi->queues = NULL; /* Erase all wait queues */
