Well, not necessarily pig.  Perhaps piglet.  We definitely need the
separate probe, shutdown and remove methods for each of our ULDs.
However, if they moved into the bus, since scsi_driver is always of type
scsi_bus, we could add separate probe, shutdown and remove fields to
struct scsi_driver and have the new fields in scsi_bus call those.  I
have to ask, though; isn't that primarily what most other bus types are
going to be doing anyway?  So doesn't it make sense to leave the fields
in the generic driver?  Then the rule becomes that if the bus has the
field, we call it, and the bus routine *may* call the corresponding
generic driver field if it feels like it.  Otherwise if the bus has no
callbacks, just use the generic driver ones?
