Subject: [PATCH] staging: netlogic: replace skb_put/pull pair with skb_reserve
Date:   Wed, 20 Mar 2019 15:45:19 +0300

Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

The sequence

    skb_put(skb);
    skb_pull(skb);

leads to the same result as

    skb_reserve(skb);

but second is a little shorter and clearer.
