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);
