Subject: [PATCH net-next 0/2] tcp: take better care of tw_substate and tw_rcv_nxt

While reviewing Jason Xing recent commit (0d9e5df4a257 "tcp: avoid reusing
FIN_WAIT2 when trying to find port in connect() process") I saw
we could remove the volatile qualifier for tw_substate field,
and I also added missing data-race annotations around tcptw->tw_rcv_nxt.

Eric Dumazet (2):
  tcp: remove volatile qualifier on tw_substate
  tcp: annotate data-races around tcptw->tw_rcv_nxt
