The main problem with Linux is that the Linux kernel is a completely unplanned
collection of individual hacks and as a result non orthogonal.
If there was a generic DMA setup call (as we have in Solaris) the DMA
for each of these logical interfaces on top of SCSI aware hardware would behave
identical.
BTW: there is even no need to add more logical interfaces than just one single
SCSI generic transport that allows to send SCSI commands to any drive that
speaks the SCSI protocol. But the Linux maintainers added unneeded interfaces
and (even worse) prohibit that the generic SCSI transport (/dev/sg*) works
for all SCSI tansport types.
