Subject: [PATCH net-next 0/8] inet: more data-race fixes

This series fixes some existing data-races on inet fields:

inet->mc_ttl, inet->pmtudisc, inet->tos, inet->uc_index,
inet->mc_index and inet->mc_addr.

While fixing them, we convert eight socket options
to lockless implementation.

Eric Dumazet (8):
  inet: implement lockless IP_MULTICAST_TTL
  inet: implement lockless IP_MTU_DISCOVER
  inet: implement lockless IP_TOS
  inet: lockless getsockopt(IP_OPTIONS)
  inet: lockless getsockopt(IP_MTU)
  inet: implement lockless getsockopt(IP_UNICAST_IF)
  inet: lockless IP_PKTOPTIONS implementation
  inet: implement lockless getsockopt(IP_MULTICAST_IF)
