Subject: [PATCH net 00/11] net: annotate data-races

This series was inspired by a syzbot/KCSAN report.

This will later also permit some optimizations,
like not having to lock the socket while reading/writing
some of its fields.

Eric Dumazet (11):
  net: annotate data-races around sk->sk_reserved_mem
  net: annotate data-race around sk->sk_txrehash
  net: annotate data-races around sk->sk_max_pacing_rate
  net: add missing READ_ONCE(sk->sk_rcvlowat) annotation
  net: annotate data-races around sk->sk_{rcv|snd}timeo
  net: add missing READ_ONCE(sk->sk_sndbuf) annotation
  net: add missing READ_ONCE(sk->sk_rcvbuf) annotation
  net: annotate data-races around sk->sk_mark
  net: add missing data-race annotations around sk->sk_peek_off
  net: add missing data-race annotation for sk_ll_usec
  net: annotate data-races around sk->sk_priority
