No it isn't natural. But sneaking such a change into your fix seems wrong.
Touching !uffd-wp code should be separate, if we want to do this at all (as
we discussed, maybe the better/cleaner approach is to eliminate writable
migration entries if possible).
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 really don't think we should do that generic change.
