Eric Dumazet 4103f8cd5c [TCP]: tcp_memory_pressure and tcp_socket are__read_mostly candidates 
tcp_memory_pressure and tcp_socket currently share a cache line with tcp_memory_allocated, tcp_sockets_allocated.
(Very hot cache line)
It makes sense to declare these variables as __read_mostly, to avoid false sharing on SMP.
