Got it, thanks (you don't actually have to summarise the argument,
merely describe the current patch).
Can you look at the scsi-misc-2.6 tree (or the current BK head plus the
scsi-misc-2.6 patch from http://parisc-linux.org/~jejb/scsi_diffs/) and
tell me what (if anything) I'm still missing?
Thanks,
James
