Subject: [Qemu-devel] [PATCH v2 0/4] qom: link property fixes
Date: Wed,  5 Mar 2014 10:40:24 +0100	[thread overview]
Message-ID: <1394012428-11678-1-git-send-email-stefanha@redhat.com> (raw)

v2:
 * A NULL set() callback should make the property read-only

There are two problems with QOM link properties:

1. There are refcount leaks in many object_property_add_link() callers.
2. There is no way to prevent link properties from being set after a device is
   realized.

This patch series fixes these issues by extending the
object_property_add_link() function.

Stefan Hajnoczi (4):
  qom: split object_property_set_link()
  qom: make QOM link property unref optional
  qom: add set() argument to object_property_add_link()
  virtio-rng: avoid default_backend refcount leak
