Subject: [PATCH net 00/11] tcp: add missing annotations

This series was inspired by one syzbot (KCSAN) report.

do_tcp_getsockopt() does not lock the socket, we need to
annotate most of the reads there (and other places as well).

This is a first round, another series will come later.

Eric Dumazet (11):
  tcp: annotate data-races around tp->tcp_tx_delay
  tcp: annotate data-races around tp->tsoffset
  tcp: annotate data-races around tp->keepalive_time
  tcp: annotate data-races around tp->keepalive_intvl
  tcp: annotate data-races around tp->keepalive_probes
  tcp: annotate data-races around icsk->icsk_syn_retries
  tcp: annotate data-races around tp->linger2
  tcp: annotate data-races around rskq_defer_accept
  tcp: annotate data-races around tp->notsent_lowat
  tcp: annotate data-races around icsk->icsk_user_timeout
  tcp: annotate data-races around fastopenq.max_qlen
