Re: [PATCH] mm/secretmem: prevent uncharged mremap expansion after fork

[Daehyeon Ko]

Thanks for the review.

Yes, this patch was developed with AI assistance. I should have included the
required Assisted-by trailer, and I apologize for the omission.

The related issue is pertinent. Lorenzo's follow-up shows that the underlying
problem is broader than the fork/mremap path: secretmem accounting follows the
VMA lifetime, while the folios remain unevictable until inode eviction. My
VM_DONTEXPAND approach only blocks one path and is not an appropriate fix.

Please drop this patch. I will test Lorenzo's follow-up patch and report the
results on that thread.

Thanks,
Daehyeon
