I like this patch.  OTOH, I couldn't help by wonder if it is possible to
somehow directly re-use the results of dv_init probing by other drivers (or
subset of the drivers, like only 'disk').  E.g. if instead of re-examining the
partition tables, we could ask a driver for a list of devices that it discovered.
But how to do that is not something that I can answer.
