Subject: [PATCH net-next 0/3] tcp: better receiver autotuning

Now TCP senders no longer backoff when a drop is detected,
it appears we are very often receive window limited.

This series makes tcp_rcv_space_adjust() slightly more robust
and responsive.

Eric Dumazet (3):
  tcp: do not overshoot window_clamp in tcp_rcv_space_adjust()
  tcp: avoid integer overflows in tcp_rcv_space_adjust()
  tcp: smoother receiver autotuning
