Subject: [PATCH net-next 0/8] tcp listener refactoring part 15

I am trying to make the final patch pushing request socks into ehash
as small as possible. In this patch series, I made various adjustments
for the SYNACK generation, allowing me to reach 1 Mpps SYNACK in my
stress test (still hitting LISTENER spinlock of course, and the syn_wait
spinlock)

I also converted the ICMP handlers a bit ahead of time :

They no longer need to get the LISTENER socket, and can use
only a lookup in ehash table. No big deal if we ignore ICMP
for requests socks before the final steps.

Eric Dumazet (8):
  inet: cache listen_sock_qlen() and read rskq_defer_accept once
  inet: remove sk_listener parameter from syn_ack_timeout()
  inet: remove some sk_listener dependencies
  net: convert syn_wait_lock to a spinlock
  ipv4: tcp: handle ICMP messages on TCP_NEW_SYN_RECV request sockets
  ipv6: tcp: handle ICMP messages on TCP_NEW_SYN_RECV request sockets
  ipv4: dccp: handle ICMP messages on DCCP_NEW_SYN_RECV request sockets
  ipv6: dccp: handle ICMP messages on DCCP_NEW_SYN_RECV request sockets
