The up-to-date flag as is now is not too useful; it tells guest_memfd not to overwrite the contents of a folio, but it doesn't say that the page is ready to be mapped into the guest. For encrypted guests, mapping a private page requires that the "preparation" phase has succeeded, and at the same time the same page cannot be prepared twice. So, ensure that folio_mark_uptodate() is only called on a prepared page. If kvm_gmem_prepare_folio() or the post_populate callback fail, the folio will not be marked up-to-date; it's not a problem to call clear_highpage() again on such a page prior to the next preparation attempt.
