    SubjectRe: [PATCH v15 00/17] Provide a zero-copy method on KVM virtio-net.

    1) Please use kernel-doc style comments to document structure

    2) The idea to key off of skb->dev in skb_release_data() is
    fundamentally flawed since many actions can change skb->dev on you,
    which will end up causing a leak of your external data areas.
