Would be great if you could send that as an individual patch, since
it's a stand-alone fix and independent from the (feature) patch set.

If there are some additional tests that are not yet covered by lib/test_bpf.c,
I'd be happy if you could add them there. This can also be as a follow-up,
but if we can increase coverage for others as well, the better.

Thanks again,
