[Patch net v3 0/4] tcp: some bug fixes for tcp_read_skb()

[Cong Wang <xiyou.wangcong@gmail.com>]

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

This patchset contains 3 bug fixes and 1 minor refactor patch for
tcp_read_skb(). V1 only had the first patch, as Eric prefers to fix all
of them together, I have to group them together. Please see each patch
description for more details.

v2: add more patches
v3: simplify empty receive queue case

Cong Wang (4):
  tcp: fix sock skb accounting in tcp_read_skb()
  tcp: fix tcp_cleanup_rbuf() for tcp_read_skb()
  tcp: refactor tcp_read_skb() a bit
  tcp: handle pure FIN case correctly
