Subject: [Patch bpf-next v1 0/4] sockmap: some performance optimizations

From: Cong Wang <cong.wang@...edance.com>

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

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()
