Thank you for having fixed the subject! Now I can apply your patches
with a clean git commit.

Do you think the build failures I reported on the v1 series are fixed
by this v2? If you think so, then I can test v2 on the autobuilders.

Also, I see this patch set is not bisectable as well as v1: you define
class TraceUnpack in patch 2 and use it in patch 1.

Best regards,
