I was really talking about overlaying the structures, which is kind of
disgusting. I wish C had inheritance like C++.

Ok. I can update the comments.

scsi_accesschk is used in the case of an array controller that provides SCSI
passthrough. In this case, you don't want scsipi touching array components.

scsi_prescan is intended for use with SCSI controllers that provide an
abstracted view of the bus, i.e. controllers that must scan the bus before
scsipi does.
