OK. I've re-based the code to work with scsi-misc and Christoph's
recent patches. I've tested it on my ia64 test mule and it appears to
function as did the previous patch.
Perhaps the target will now stand still for a while? :)
Attached is version 1f of the patch. Previous versions should
be disregarded.
