函数名称：Caller needs to wrap with rcu_read_(un)lock()

函数原型：static inline struct tcp_fastopen_context *tcp_fastopen_get_ctx(const struct sock *sk)

返回类型：struct tcp_fastopen_context

参数：

类型参数名称
const struct sock *sk
1679  ctx等于cu_dereference() - fetch RCU-protected pointer for dereferencing*@p: The pointer to read, prior to dereferencing* This is a simple wrapper around rcu_dereference_check().(cipher context for cookie )
1680  如果非ctx则ctx等于cu_dereference() - fetch RCU-protected pointer for dereferencing*@p: The pointer to read, prior to dereferencing* This is a simple wrapper around rcu_dereference_check().(tcp_fastopen_ctx)
1682  返回:ctx
