[Qemu-devel] [PATCHv2 0/5] virtio: cleanup layout assumptions

["Michael S. Tsirkin" <mst@redhat.com>]

This patchset helps remove the assumption that vdev must be the 1st
member in any virtio device implementation. Other assumptions (made by
qdev) can be removed in a similar way separately, this patchset does not
do this yet.

We also make it obvious that all of device structure is zero
initialized, which devices seem to rely on, by virtue of
calling mallocz directly in device code.

Note how code is simplified rather than made more complex.

Changes from v1:
	Get rid of VIRTIO_COMMON_INIT macro:
	simple function call, no magic now.

Michael S. Tsirkin (5):
  virtio: add type safe API
  virtio-net: remove layout assumptions
  virtio-serial: remove struct layout assumptions
  virtio-balloon: remove layout assumptions
  virtio-blk: remove layout assumption
