The benefit is that tcm_loop will show up in the system as a 'real'
SAS hba; long-term goal is to simulate SAS multipathing here.
I was even planning on adding simlated FC infrastructure, too;
with that we could simulate FC multipathing, too, and our QA would
be _so_ happy...

Again, these patches are mainly a collection of patches I've done to
test various scenarios, in the hope others might find them useful,
too. So I can easily hold off these patches until you've posted your
rework.

Cheers,

Hannes
