Yep, Fuad is currently trying to port the pKVM mm stuff on top of this series to see how well it fits, so stay tuned. I think there is still some room for discussion around page conversions (private->shared etc), and we'll need a clearer idea of what the code might look like to have a constructive discussion, but so far it does seem like using a memfd (the new private one or perhaps just memfd_secret, to be discussed) + memfd notifiers is a promising option.
