Guys, this isn't helpful.

We aren't extending anon_vma, and I am working on replacing it, that's the
bottom line.

I have presented compelling evidence suggesting this is AI generated. In
response I got more AI-generated nonsense. There's no trust, the code and
analysis are all wrong, end of discussion.

P.S. maintainership is utterly thankless, and I don't really expect much in

really quite disappointing.
