I understand Krzysztof, but since my 34-patchset should be ready and I don't
expect to send any v6 for how it is right now, your patch would make it
necessary to send yet another patchbomb on my side... we're kind-of in the
same situation here, and I feel like we're making a big issue out of something
that should not really be a problem.

I'm sorry about this situation, and I feel like this doesn't really depend
on me, as much as it doesn't really depend on you... let's just see what CK
thinks about this, or else, I don't know how to make this easier on all of
us - me, you and the maintainer.

If it felt like me being rude in any way, that wasn't my intention, btw.

I can offer to rebase this patch on my own keeping your authorship, if that
makes things easier.

Cheers,
Angelo
