I would like to flag that at some stage in the future the SCSI (or whatever it may be called) subsystem will need to support true bidirectional commands (there are a few of these in SBC-2 and lots of them in OSD). To do it properly I think we need two scatter gather lists, one for data out (to the device) and one for data in (from the device). The SBC-2 XDWRITEREAD command indicates that the data out is done before the data in (from the device); I'm not sure whether that ordering is always the case.
