Would that fit your case? I suspect it depends > on locking, for example whether you have to revoke while holding > memory_lock. I was keeping that hack *entirely* separate from the guest_memfd work. That's a quirk on the IOAS in iommufd: "whenever you unmap, put *this* page in its place instead". It doesn't belong anywhere near what we're doing here, ideally. I even talked to Jason about it about it at LPC, and he didn't hurt me. If we implement a hitless=C2=B9 REPLACE operation then the scratch-page end= s up being a fairly trivial thing to redirect UNMAP to REPLACE (the tricksy detail being that it uses the *same* scratch page for every IOVA in the range). =C2=B9 why do we call it that? Shouldn't it be 'missless'? --=-NGhcf2IBb+AIA0wX4/rS Content-Type: application/pkcs7-signature; name="smime.p7s" Content-Disposition: attachment; filename="smime.p7s" Content-Transfer-Encoding: base64
