bk8.good.always.patch is the name I have stored locally for that patch.

Among our blogged results we of course still have the noise of
brain-dead newbie errors by me.

I'll roll back to vanilla -bk8, apply my bk8.good.always.patch, and
reconfirm results of:

#
# host expects no data, device agrees

sudo plscsi /dev/sg0 -v -X time 5 0 -x "12 00:00:00 00 00"

sudo plscsi /dev/sg0 -v -X time 5 0 -x "00 00:00:00 00 00"

#
# host expects one block in, device actually sources no data

sudo plscsi /dev/sg0 -v -X time 5 0 -i x800 -x "28 00 00:00:00:10 00 00:00 00"

#
# host expects one block out, device actually sinks no data

sudo plscsi /dev/sg0 -v -X time 5 0 -o x800 -x "2A 00 00:00:00:10 00 00:00 00"
