[Qemu-devel] [PATCH v2 0/4] qdev: remove all remaining cannot_destroy_wi

Subject: [Qemu-devel] [PATCH v2 0/4] qdev: remove all remaining cannot_destroy_with_object_finalize_yet
Date: Fri, 14 Apr 2017 10:37:13 +0200

This series removes all the remaining uses of
cannot_destroy_with_object_finalize_yet to finally remove
the flag itself.

The ARM patch has already been sent alone and reviewed by Markus.
I have tested the ppc one on ppc64 machine with KVM and using
QDM device-list-properties command.

For the versatile one, the flag allowed to workaround a problem
in the bus unparent function: the bus unparent is trying to
unparent all the children of the bus. To do that, it has a list
of the children of the bus, and calls object_unparent() for each
child, and object_unparent() calls object_property_del_child() if
obj->parent is not NULL.  As qdev_set_parent_bus() set only
parent_bus and the list of children, parent is NULL and the child
is never deleted.  We can avoid the problem by moving the
qdev_set_parent_bus() to the realize part.

I've tested all the changes with "make check" (including
device-introspect-test). I've booted a versatilepb machine
with a 3.16.0-4 debian installer kernel.
