Subject: [PATCH] rdma: Fix block during rdma migration
If the networking break or there's something wrong with rdma
device(ib0 with no IP) during rdma migration, the main_loop of
qemu will be blocked in rdma_destroy_id. I add rdma_ack_cm_event
to fix this bug.

Good catch. =) That's an obvious bug. It looks like I need
to do a much better job of "kill -9" inside the regression
testing scripts - probably i should try killing the migration
prematurely at different periods just to be sure there are
no more places where the connection state is not getting
cleaned up......

Sorry for the late reply, but I'm not the maintainer for migration,
that's Juan
(I can only signoff on patches like everyone else =).
I also have outstanding RDMA patches myself that have not yet been pulled.
Would you mind pinging Juan for both of us?

The patch is Cc'ing Juan, maybe he is very busy.
I have post v2 even, but I have not gotten any reply.
I have no idea how to do next.
