I'm not worried about transition cost (that's for whoever makes the

For example, it might be done using mmu notifiers. We might use the
existing madvise(MADV_DONTNEED) as the entry point (though I don't
know how we would indicate deflation).
I guess we could extend mmu notifiers to notify on any PTE transition,
but that seems like a lot of VM complexity for a little gain, given
the simple KVM-internal alternatives.
mmu notifiers already notify on any pte transition.
