+Differences from v3:\r
+\r
+ - squashed patches; take it up with Jani\r
+ - address some review comments (interdiff follows)\r
+ - some stylistic things I left for someone who cares\r
+ (either I tried it and didn't like it, or disagree with the premise)\r
+ - split doc and test patches so series can be partially applied\r
+ without --folder or --create-folder options\r
