I tried to look up that commit:
48ae8484e9fc ("scsi: sg: don't return bogus Sg_requests")
but that isn't in Linus' tree. Even searched for just the title, still
didn't find anything.
I'm assuming this is a bug in the sg.c driver, in which case the 2/3
prep and real test case looks fine. For generic device testing, we
should just use SG_IO and not bother with sg.c at all. The world would
be a better place if we could just get rid of sg.c...
