So I finally have a test system up and running. I have good and bad news. The
good news is, I can't get the system crashing with my patches, the bad news is
I can't get zfcp_ping and zfcp_show to output something but HBA_STATUS_ERROR
with my patches and without.

And btw, I renamed the branch to fc-bsg-rewrite-v4 in case you want to clone
from it (it has patch 2/16 changed to the v3 submission).

Can you please have a look with your setup?

Thanks,
Johannes
