sk_wait_data9
Wait for data to arrive at sk_receive_queue
Usage
int sk_wait_data(struct sock * sk, long * timeo, const struct sk_buff * skb);
Arguments
sk
sock to wait on
timeo
for how long
skb
last skb seen on sk_receive_queue
Overview
Now socket state including sk->sk_err is changed only under lock, hence we may omit checks after joining wait queue. We check receive queue before schedule only as optimization; it is very likely that release_sock added new data.
