I mean the interface that any user of an object should
use to access properties, ie object_property_set()
and object_property_get(). Something like:
static void balloon_pci_fwd_get(Object *obj,
struct Visitor *v, void *opaque, const char *name, Error **errp)
{
VirtIOBalloonPCI *dev = VIRTIO_BALLOON_PCI(obj);
object_property_get(OBJECT(&dev->vdev), v, name, errp);
}
Ditto for fwd_set; note that you can use the same accessors
for any property you need to forward to the underlying
virtio-balloon-device. Untested :-)
