If you see I made the subject as mm/migrate, because I took it as a migration change, not uffd-wp specific. I also added the Fixes to the uffd patch because afaict that's the only thing that it affects, but I can't tell either. As I said, I'm trying to follow the rule where we have read entry I want to make sure write bit removed. I hope we have this patch land soon, because it affects users. I'm not against further rework on migration entries as I replied in the other email, but for this patch I keep the same thoughts as when I posted. Thanks, -- Peter Xu
