Subject: [PATCH net-next 0/6] tcp: set few options locklessly

This series is avoiding the socket lock for six TCP options.

They are not heavily used, but this exercise can give
ideas for other parts of TCP/IP stack :)

Eric Dumazet (6):
  tcp: set TCP_SYNCNT locklessly
  tcp: set TCP_USER_TIMEOUT locklessly
  tcp: set TCP_KEEPINTVL locklessly
  tcp: set TCP_KEEPCNT locklessly
  tcp: set TCP_LINGER2 locklessly
  tcp: set TCP_DEFER_ACCEPT locklessly
