6   This function creates a clone of a buffer that holds a reference on
7   sk_refcnt.  Buffers created via this function are meant to be
8   returned using sock_queue_err_skb, or free via kfree_skb.
9   </p><p>
10
11   When passing buffers allocated with this function to sock_queue_err_skb
12   it is necessary to wrap the call with sock_hold/sock_put in order to
13   prevent the socket from being released prior to being enqueued on
14   the sk_error_queue.
