Thank you for your work.

IMHO, all your patches can be merged in only one. Morever it would help for review as some patches 
remove code done in previous patches.

The "v2" tag is missing in the subject of the patches of your series.

And don't send a series as a reply of a previous one.

You can use "git-publish" it helps a lot when we have to send several versions of a series.

Thanks,
Laurent
