Subject: [PATCH v3 net-next 0/2] tcp/dccp: remove 16 bytes from icsk

icsk->icsk_timeout and icsk->icsk_ack.timeout can be removed.

They mirror existing fields in icsk->icsk_retransmit_timer and
icsk->icsk_retransmit_timer.

v2,v3: rebase, plus Kuniyuki tags.

Eric Dumazet (2):
  tcp/dccp: remove icsk->icsk_timeout
  tcp/dccp: remove icsk->icsk_ack.timeout
