This patchset contains two optimizations for sockmap. The first one
eliminates a skb_clone() and the second one eliminates a memset(). With 
this patchset, the throughput of UDP transmission via sockmap gets
improved by 61%.

v3: avoid touching tcp_recv_skb()

v2: clean up coding style for tcp_read_skb()
    get rid of some redundant variables
    add a comment for ->read_skb()

---

Cong Wang (4):
  tcp: introduce tcp_read_skb()
  net: introduce a new proto_ops ->read_skb()
  skmsg: get rid of skb_clone()
  skmsg: get rid of unncessary memset()
