Though I vote for KVM_MEM_GUEST_MEMFD (or KVM_MEM_GUEST_MEMFD_VALID or KVM_MEM_USE_GUEST_MEMFD). I.e. do our best to avoid ambiguity between referring to "guest memory" at-large and guest_memfd.
I was going to propose KVM_MEM_HAS_GUESTMEMFD. Any option is okay for me so, if no one complains, I'll go for KVM_MEM_GUESTMEMFD (no underscore because I found the repeated "_MEM" distracting).
