Sorry, I was wrong. ignore the comments about cgroups. That's still
broken. (i.e. trying to register RDMA memory while using a cgroup swap
limit cause the process get killed).
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).
Am I missing something? I was only testing the GIFT flag patch.
Note: I only turned it on - I did not verify the (non) consitency of the
memory that was transmitted.

Not sure I'm interpreting this correctly. Are you saying that things
worked without actually setting the GIFT flag? In which case why are
we adding this flag?
