There is no difference compared to (implicit) v1 sent a few minutes
earlier, right? There was another patch sent with the same Subject last
week, so I assume the mail from today without "v2" in the Subject was a
mistake?

Adding a paragraph below the tripple dash that points out what was
changed compared to the previous submission is a good idea to help
reviewers to more easily see what was changed. I guess you only adapted
the commit log as a reaction to Matthias Burgger's review?

Best regards
Uwe
