I'm so sorry! So I have a pure (and even stupid) question to ask before the rest of details.. it's pure question because I know little on guest_memfd, especially on the future plans. So.. Is there any chance guest_memfd can in the future provide 1G normal (!CoCo) pages? If yes, are these pages GUP-able, and mapp-able? Thanks, -- Peter Xu
