Subject: [PATCH net-next 0/3] inet: tcp listener refactoring part 14

OK, we have serious patches here.

We get rid of the central timer handling SYNACK rtx,
which is killing us under even medium SYN flood.

We still use the listener specific hash table.

This will be done in next round ;)

Eric Dumazet (3):
  inet: drop prev pointer handling in request sock
  inet: get rid of central tcp/dccp listener timer
  net: increase sk_[max_]ack_backlog
