Merge branch 'tcp-annotate-data-races-around-icsk_retransmits-and-icsk_probes_out'
Eric Dumazet says:
====================
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.
====================
