> Currently, if a connect call fails on a signal or timeout (e.g., guest is still
> in the process of starting up), we'll just return to caller and leave the connect
> packet queued and they are sent even though the connection is considered a failure,
> which can confuse applications with unwanted false connect attempt.

> The patchset enables vsock (both host and guest) to cancel queued packets when
> a connect attempt is considered to fail.

> v5 changelog:
>   - change virtio_vsock_pkt->cancel_token back to virtio_vsock_pkt->vsk
> v4 changelog:
>   - drop two unnecessary void * cast
>   - update new callback comment
> v3 changelog:
>   - define cancel_pkt callback in struct vsock_transport rather than struct virtio_transport
>   - rename virtio_vsock_pkt->vsk to virtio_vsock_pkt->cancel_token
> v2 changelog:
>   - fix queued_replies counting and resume tx/rx when necessary

Series applied, thanks.
