Hmm. I don't think we should even attach the alua handler in this case,
e.g. refine the check in scsi_dh_find_driver. But then again I don't
remember how the spec wording actually disallows this, and a quick grep
of SPC-4 can't find anything either. Can you put a reference to the spec
section that disallows attachment to non-disk devices into the code?

And does it really allow RBC (but not ZBC)?
