Sorry, I was wrong. ignore the comments about cgroups. That's still broken.The point of the GIFT patch is to avoid triggering copy-on-write so

But the GIFT flag patch works (my understanding is that GIFT flag allows the
adapter to transmit stale memory information, it does not have anything to
do with cgroups specifically).
that memory doesn't blow up during migration. If that doesn't work
then there's no point to the patch.
