Just one overall comment on process:

When resending patches _always_ mention what you've changed compared to
the last version. Specifically call out which review comments you've
incorporated and even more important which one's you've decided to
implement differently or rejected.

The preferred form for that is with a per-patch changelog in the commit
message. Also mentioned the reviewer's name if the change is due to
review.

For bigger reworks that affect the entire patch series please also mention
them in the cover letter.

I'll update our internal BKMs with this information.

Thanks, Daniel
