Roland, Series looks good AFAICT. Thanks for nailing this nasty and long standing issues.

Agreed. You often write very thoughtful commit messages, but unfortunately for future reference commit messages can only be seen through git blame, and until any refactory completely hides them away. It would be preferable to have the detailed explanation as comments, and merely say "See code comments for details" in the commit messages.
