    I severely doubt this, the bulk of the overhead of
    skb_put() is the atomic operation, not whether the
    instructions get executed inline or not.

    Please run some tests before making claims like this.
    I might give you some slack in this area if you've
    been doing networking performance tuning for 10+ years
    but you haven't.
