Yes, the intent is for this to serve as a reproducer for the WARN rather
than a pass/fail regression test. A clear pass/fail verdict would be
preferable, but that does not seem feasible here since EFAULT is
returned regardless of the patch.

Another option would be to add a KUnit test for the negative optlen
validation, but that seemed excessive for this fix.
