When rebasing patches and especially like here when also renaming them a
bit please leave some indication of what you've changed. Took me a while
to figure out where one of my pending comments from the previous round
went too.
And please don't just "v2: rebase", but please add some indicators against
what it conflicted if it's obvious.
Thanks, Daniel
