From b42c591fec6dad8dab0133c6da5b8f35358d5b66 Mon Sep 17 00:00:00 2001
From: "Daniel P. Berrange" <berrange@redhat.com>

Subject: [PATCH] admin: add support for post-exec restart callbacks

We don't have any per-client private data we need to persist, but the
RPC infrastructure requires that we provide the callbacks and serialize
an empty JSON object. This makes us future proof going forwards.
