Hey Ingo-

Are you willing to back this out and replace it with a version that
I'm going to send in about two minutes?  This version is missing most
of Borislav's review comments annd has a crappy changelog message.  Or
have you already sent it to Linus?

Or I can rebase on top, but it's messy and it won't fix the changelog.
