[Qemu-devel] [PATCH v3 0/5] qom: link property fixes

[Stefan Hajnoczi <stefanha@redhat.com>]

v3:
 * Split first commit for easier reviewing [afaerber]
 * Turn bool argument into flags bitmask [pbonzini]
 * Rename set() callback to check() [pbonzini]
 * Rename object_property_default_set_link() to
   object_property_allow_set_link()
 * Rename qdev_prop_default_set_link() to
   qdev_prop_allow_set_link_before_realize()

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 (5):
  qom: split object_property_set_link()
  qom: don't make link NULL on object_property_set_link() failure
  qom: make QOM link property unref optional
  qom: add check() argument to object_property_add_link()
  virtio-rng: avoid default_backend refcount leak
