From 39f72ef94ba74701d18daf82b44c18a60f94eb60 Mon Sep 17 00:00:00 2001 From: Stefan Hajnoczi Date: Wed, 19 Mar 2014 08:58:56 +0100 Subject: qom: Add check() argument to object_property_add_link() MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit There are currently three types of object_property_add_link() callers: 1. The link property may be set at any time. 2. The link property of a DeviceState instance may only be set before realize. 3. The link property may never be set, it is read-only. Something similar can already be achieved with object_property_add_str()'s set() argument. Follow its example and add a check() argument to object_property_add_link(). Also provide default check() functions for case #1 and #2. Case #3 is covered by passing a NULL function pointer. Cc: Peter Crosthwaite Cc: Alexander Graf Cc: Anthony Liguori Cc: "Michael S.
