返回类型：int

参数：

类型参数名称
struct selinux_avc *avc
char *page
156  _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
158  slots_used等于0
159  max_chain_len等于0
160  以i小于AVC_CACHE_SLOTS循环
161  head等于 head for avc_node->list [i]
162  如果非hlist_empty(head)则
163  slots_used自加
164  chain_len等于0
165  hlist_for_each_entry_rcu - iterate over rcu list of given type*@pos: the type * to use as a loop cursor.*@head: the head for your list.*@member: the name of the hlist_node within the struct.(node, head, list)
166  chain_len自加
167  如果chain_len大于max_chain_len则max_chain_len等于chain_len
172  _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()
174  返回:格式化输出字符串
