Hm, still behaves for me like I reported for v2:

The rational behind this is, in fc_req_to_bsgjob() we're assigning
job->request as req->cmd and job->request_len = req->cmd_len. But without
checkinf job->request_len we don't know whether we're save to touch
job->request (a.k.a. bsg_request).

Hi Steffen,
Did you have any chance testing this? I hacked fcping to work with non-FCoE
and rports as well and tested with FCoE and lpfc. No problems seen from my
side. I've also pused the series (With this change folded in) to my git 
tree at [1] if this helps you in any way.

[1] https://git.kernel.org/cgit/linux/kernel/git/jth/linux.git/log/?h=scsi-bsg-rewrite-v4

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
