reviewed again. I still don't like this as it introduces an unbalanced weighting for the vfio dd but ... We could consider removing the if (ap_drv->flags & AP_DRIVER_FLAG_DEFAULT) return 0; in function __verify_queue_reservations. It would still work as the 'default device drivers' do not implement the in_use() callback and thus do not disagree about the upcoming change.
I don't have a problem with that given the default drivers may one day have use for implementing the callback.
