函数名称：smack_from_secid - find the Smack label associated with a secid*@secid: an integer that might be associated with a Smack label* Returns a pointer to the appropriate Smack label entry if there is one,* otherwise a pointer to the invalid Smack label.

函数原型：struct smack_known *smack_from_secid(const unsigned int secid)

返回类型：struct smack_known

参数：

类型参数名称
const unsigned intsecid
596  _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
598  如果smk_secid恒等于secid则
599  _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()
600  返回:skp
608  _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()
