[Qemu-devel] [PATCH 00/11] virtio migration: simplify vmstate helper

[Halil Pasic]

As a part of the long term  effort to convert migration to vmstate the
migration of virtio devices was recently partially switched to vmstate
starting with the outer layer (commit 5943124cc "virtio: Migration
helper function and macro" and the subsequent "virtio-*: Wrap in
vmstate" commits). This was done by introducing a vmstate based wrapper
driving the well know virtio migration process. As this transition is
still in progress, some synergies were left unexploited, and some things
can be expressed in a more vmstatish way.

Let us simplify a couple of things and get rid of some code duplication.

Did only a couple of smoke tests. Comprehensive testing is still to be done.

Halil Pasic (11):
  virtio: add VIRTIO_DEF_DEVICE_VMSD macro
  virtio-blk: convert to VIRTIO_DEF_DEVICE_VMSD
  virtio-net: convert to VIRTIO_DEF_DEVICE_VMSD
  virtio-9p: convert to VIRTIO_DEF_DEVICE_VMSD
  virtio-serial: convert to VIRTIO_DEF_DEVICE_VMSD
  virtio-gpu: do not use VMSTATE_VIRTIO_DEVICE
  virtio-input: convert to VIRTIO_DEF_DEVICE_VMSD
  virtio-scsi: convert to VIRTIO_DEF_DEVICE_VMSD
  virtio-balloon: convert to VIRTIO_DEF_DEVICE_VMSD
  virtio-rng: convert to VIRTIO_DEF_DEVICE_VMSD
  virtio: remove unused VMSTATE_VIRTIO_DEVICE
