I decided to just apply that patch. It is *not* marked for stable, very intentionally, because I expect that we will need to wait and see if there are issues with it, and whether we might have to do something entirely different (more like the traditional behavior with some extra "only for owner" logic). But doing a test patch during the merge window (which is about to close) sounds like the right thing to do. Linus
