The virtio-vsock device specification is not finalized yet. Michael Tsirkin voiced concerned about merging this code when the hardware interface (and possibly the userspace interface) could still change. Please revert for now. I am working to finalize the virtio-vsock device specification and at that point the interfaces will be stable. Stefan Hajnoczi (6): Revert "VSOCK: fix
