函数名称:sk_psock_get

函数原型:static inline struct sk_psock *sk_psock_get(struct sock *sk)

返回类型:struct sk_psock

参数:

类型参数名称
struct sock *sk
422  _read_lock() - mark the beginning of an RCU read-side critical section* When synchronize_rcu() is invoked on one CPU while other CPUs* are within RCU read-side critical sections, then the* synchronize_rcu() is guaranteed to block until after all the other
423  psock等于sk_psock(sk)
424  如果psock且非_inc_not_zero - increment a refcount unless it is 0*@r: the refcount to increment* Similar to atomic_inc_not_zero(), but will saturate at REFCOUNT_SATURATED* and WARN.* Provides no memory ordering, it is assumed the caller has guaranteed thepsock = NULL
426  _read_unlock() - marks the end of an RCU read-side critical section.* In most situations, rcu_read_unlock() is immune from deadlock.* However, in kernels built with CONFIG_RCU_BOOST, rcu_read_unlock()
427  返回:psock
