Looks good to me, a few comments:
1) I agree with Pavel that the WARN on overflow is kinda silly,
it doesn't matter that much. So I'd rather drop those for now.
2) Would really love it to see some decent commit messages, quite
a few of them are empty. In general some reasoning is nice in
the commit message, when you don't have the context available.
Do you want to do a v4 with 5-6/6 dropped for now, and 3-4 having
some reasoning? I can also just apply as-is and write some commit
message myself, let me know. I'll add 1-2 for now.
