[Qemu-devel] [PATCH v2 0/7] qdev: Introduce DEFINE_PROP_LINK

[Fam Zheng]

v2: Create a new header for link properties. [Paolo]
    Don't wrap, use PropertyInfo.create() (much better diffstat, yay!).
    [Paolo]

Link properties of devices created with object_property_add_link() are not
reflected in HMP "info qtree". For example, whether a virtio-blk device has an
iothread (i.e. has enabled data plane) can not be introspected easily.

Introduce a new type of qdev property macro to fix that.

Fam Zheng (7):
  qom: Make link property API public
  qom: Handle property lookup failure in object_resolve_link
  qdev: Introduce PropertyInfo.create
  qdev: Introduce DEFINE_PROP_LINK
  virtio-blk: Use DEFINE_PROP_LINK
  virtio-scsi: Use DEFINE_PROP_LINK
  virtio-rng: Use DEFINE_PROP_LINK
