net: sk_sleep() helper
Eric Dumazet [Tue, 20 Apr 2010 13:03:51 +0000 (13:03 +0000)]
Define a new function to return the waitqueue of a "struct sock".

static inline wait_queue_head_t *sk_sleep(struct sock *sk)
{
return sk->sk_sleep;
}

Change all read occurrences of sk_sleep by a call to this function.

Needed for a future RCU conversion. sk_sleep wont be a field directly
available.
