ide-{floppy,scsi} are using 'request_transfer', 'actually_transferred',
'buffer_size' and 'current_position' in their packet command structures.
We are going to unify ATAPI packet command handling for all ATAPI
device drivers and this patch is a change in the opposite direction.
(IOW I suggest to drop it until ATAPI handling gets unified).
Thanks,
Bart
