返回类型：int

参数：

类型参数名称
struct smack_parsed_rule *srp
struct list_head *rule_list
struct mutex *rule_lock
216  found等于0
217  rc等于0
219  mutex_lock(rule_lock)
226  如果smk_object恒等于smk_object且smk_subject恒等于smk_subject则
228  found等于1
229  smk_access或等于smk_access1
230  smk_access与等于smk_access2的反
231  退出
235  如果found恒等于0则
236  sp等于Shortcuts
237  如果(sp == NULL)则
238  rc等于负ENOMEM
239  转到:out
242  smk_subject等于smk_subject
243  smk_object等于smk_object
244  smk_access等于smk_access1按位与smk_access2的反
246  添加RCU保护项
249  out :
250  mutex_unlock - release the mutex*@lock: the mutex to be released* Unlock a mutex that has been locked by this task previously.* This function must not be used in interrupt context. Unlocking* of a not locked mutex is not allowed.
