      get_maintainers.pl does not handle parenthesis in maintenance areas well
in connection with list emails (here: qemu-ppc@nongnu.org).

Resolve a recurring CC issue breaking git-send-email by reverting part
of commit 085eb217 ("Add David Gibson
for sPAPR in MAINTAINERS file").

      qdev: Free QemuOpts when the QOM path goes away · abed886e
      由 Paolo Bonzini 提交于 
      Otherwise there is a race where the DEVICE_DELETED event has been sent but
attempts to reuse the ID will fail.

Note that similar races exist for other QemuOpts, which this patch
does not attempt to fix.

For example, if the device is a block device, then unplugging it also
deletes its backend.  However, this backend's get deleted in
drive_info_del(), which is only called when properties are
destroyed.  Just like device_finalize(), drive_info_del() is called
some time after DEVICE_DELETED is sent.  A separate patch series has
been sent to plug this other bug.  Character devices also have yet to
be fixed.

      qom: Change object property iterator API contract · 7746abd8
      由 Daniel P. Berrange 提交于 
      Currently the ObjectProperty iterator API works as follows:

  ObjectPropertyIterator *iter;

  iter = object_property_iter_init(obj);
  while ((prop = object_property_iter_next(iter))) {
     ...
  }
  object_property_iter_free(iter);

This has the benefit that the ObjectPropertyIterator struct
can be opaque, but has the downside that callers need to
explicitly call a free function. It is also not in keeping
with iterator style used elsewhere in QEMU/GLib2.

This patch changes the API to use stack allocation instead:

  ObjectPropertyIterator iter;

  object_property_iter_init(&iter, obj);
  while ((prop = object_property_iter_next(&iter))) {
     ...
  }

      qom: Allow properties to be registered against classes · 16bf7f52
      由 Daniel P. Berrange 提交于 
      When there are many instances of a given class, registering
properties against the instance is wasteful of resources. The
majority of objects have a statically defined list of possible
properties, so most of the properties are easily registerable
against the class. Only those properties which are conditionally
registered at runtime need be recorded against the klass.

Registering properties against classes also makes it possible
to provide static introspection of QOM - currently introspection
is only possible after creating an instance of a class, which
severely limits its usefulness.

This impl only supports simple scalar properties. It does not
attempt to allow child object / link object properties against
the class. There are ways to support those too, but it would
make this patch more complicated, so it is left as an exercise
for the future.

There is no equivalent to object_property_del() provided, since
classes must be immutable once they are defined.
