Thanks David :)

I am now working on sk_callback_lock case, to speedup
sock_def_readable(), sock_def_write_space() in typical cases
(SOCK_FASYNC not set)

Instead of using rcu on whole "struct socket", my plan is to use a small
structure :

struct wait_queue_head_rcu {
	wait_queue_head_t wait;
	struct rcu_head	  rcu;
} ____cacheline_aligned_in_smp;

and make sk->sk_sleep points to this 'wait' field.
