H A Dskbuff.rst15 Shared skbs and skb clones
19 to keep a struct sk_buff alive. skbs with a ``sk_buff.users != 1`` are referred
20 to as shared skbs (see skb_shared()).
22 skb_clone() allows for fast duplication of skbs. None of the data buffers
24 &skb_shared_info.refcount indicates the number of skbs pointing at the same
