That will explain it, yes. In the same way for correctness also those should
be converted from request_fn to generic_unplug_device, right? (this
will also avoid to recall spurious request_fn because the device is still in the
tq_disk queue even when the I/O generated by the below request_fn completed)

        if (major >= COMPAQ_SMART2_MAJOR+0 && major <= COMPAQ_SMART2_MAJOR+7)
                (q->request_fn)(q);
        if (major >= DAC960_MAJOR+0 && major <= DAC960_MAJOR+7)
                (q->request_fn)(q);
