Please do not claim authorship of patches that haven't been authored
by you. Of course, there is a balance, if you need to make bigger
modifications, then you deserve to claim the authorship, but that
isn't the case here I think.

This applies to a couple of more patches in the series, I will not
comment on them in this regard, but leave that to you to look over at
the next submission.

I appreciate the version history per patch. However, this doesn't
belong in the commit message.

Instead you have to manually edit each formatted patch to add this,
exactly where see below.

After this line you can add comments and version history for the
patch. In this way, it will not be a part of the commit message when
applying.

Complete the section by adding three new dashes and a newline - this
keeps the patch format correct.
