Hmm as far as I can see, there's no build issue.
My patch is required before Marcel's one.
Then there's another one by me to address the comments
you had.

I could squash them all but this just messes up attribution,
bisect build is fine, and I verified that.

I certainly didn't intend to blame anyone, sorry if it
sounded like that. I was merely saying, it's been on review
for a while, got ack and not objections, so let's apply it unless
someone sees significant issues, I don't want to hold it up
until all questions are answered.
