[Qemu-devel] [PATCH 0/2] dataplane: fix start/stop races

[Michael S. Tsirkin]

This works around races that data plane introduces
simply by exiting immediately if we detect
that dataplane is active.

It's a small but ugly patch, it's only justification
is that it's minimally intrusive, and that it clearly
has no chance to break non data plane users.

The idea is to rework it all post 2.6.

  virtio: add aio handler
  virtio-blk: use aio handler for data plane
