In this series, I split all kinds of reasons into five part which, I
think, can be easily reviewed. I respectively implement corresponding
rstreasons in those functions. After this, we can trace the whole tcp
passive reset with clear reasons.

Jason Xing (5):
  tcp: fully support sk reset reasons in tcp_rcv_synsent_state_process()
  tcp: fully support sk reset reason in tcp_ack()
  tcp: fully support sk reset reason in tcp_rcv_state_process()
  tcp: handle timewait cases in rstreason logic
  tcp: handle rstreason in tcp_check_req()
