Ccing couple more folks who are doing similar work (ASI, guest_memfd) Folks, what is the generic way to check if a given mapping has folios unmapped from kernel address space?
Can't we just lookup the mapping and refuse these folios that really shouldn't be looked at?
See gup_fast_folio_allowed() where we refuse secretmem_mapping(). -- Cheers, David / dhildenb
