Might help to send it to linux-scsi to get people to review and apply it
But that patch looks good to me, avoiding one allocation for each
command and simplifying the code. I try to remember why these were
two slabs to start with but can't find any reason.
Btw, we might just want to declare the sense buffer directly as a sized
array in the scsi command as there really doesn't seem to be a reason
not to allocate it.
