[Qemu-devel] [PATCH 00/11] qdev: correct reference counting


From: Paolo Bonzini
Subject: [Qemu-devel] [PATCH 00/11] qdev: correct reference counting
Date: Wed, 5 Dec 2012 21:44:31 +0100

This series makes the ref_count field of device and bus objects actually
match the number of references that the objects have.  Once this is done,
qdev_free and qbus_free are equivalent to simply object_unparent, and
object_delete can go.

Patches 1-3 fix some warts in the last minute patches that went in 1.3.
Patches 4-9 are the bulk of the series.  Patches 10-11 touches the CPU
classes instead.

Paolo Bonzini (11):
  qdev: export and use qbus_init
  qdev: use object_new, not g_malloc to create buses
  qom: preserve object while unparenting it
  qdev: add reference count to a device for the BusChild
  qdev: move deletion of children from finalize to unparent
  qdev: move unrealization of devices from finalize to unparent
  qdev: add reference for the bus while it is referred to by the
    DeviceState
  qdev: inline object_delete into qbus_free/qdev_free
  qdev: drop extra references at creation time
  cpu: do not use object_delete
  qom: remove object_delete
