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 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 hw/pci.c | 11 +++--- hw/pci.h | 5 --- hw/qdev-core.h | 1 + hw/qdev-monitor.c | 5 ++- hw/qdev.c | 107 +++++++++++++++++++++++++++++--------------------- hw/sysbus.c | 6 +-- include/qemu/object.h | 17 +------- linux-user/syscall.c | 2 +- qom/object.c | 9 +---- target-i386/helper.c | 4 +- target-sparc/cpu.c | 2 +- vl.c | 1 + 12 files changed, 84 insertions(+), 86 deletions(-) -- 1.8.0.1
