[Qemu-devel] [PATCH v6 02/11] qom: don't require user creatable objects to be registered

[Daniel P . Berrangé]

When an object is in turn owned by another user object, it is not
desirable to expose this in the QOM object hierarchy, as it is
just an internal implementation detail, we should be free to change
without exposure.
