Subject: [PATCH net-next 0/2] tcp: annotate data-races around icsk_retransmits
 and icsk_probes_out

icsk->icsk_retransmits is read locklessly from inet_sk_diag_fill(),
tcp_get_timestamping_opt_stats, get_tcp4_sock() and get_tcp6_sock().

icsk->icsk_probes_out is read locklessly from inet_sk_diag_fill(),
get_tcp4_sock() and get_tcp6_sock().

Add corresponding READ_ONCE()/WRITE_ONCE() annotations.

Eric Dumazet (2):
  tcp: annotate data-races around icsk->icsk_retransmits
  tcp: annotate data-races around icsk->icsk_probes_out
