参数：

类型参数名称
struct kprobe *ap
struct kprobe *p
1324  Keep all fields in the kprobe consistent
1325  flush_insn_slot(ap)
1326  location of the probe point 等于 location of the probe point
1327  * Indicates various status flags. * Protected by kprobe_mutex after this kprobe is registered.等于* Indicates various status flags. * Protected by kprobe_mutex after this kprobe is registered.按位与probe is really optimized.* NOTE:* this flag is only for optimized_kprobe.的反
1328  Called before addr is executed. 等于aggr_pre_handler
1329  * ... called if executing addr causes a fault (eg. page fault). * Return 1 if it handled fault, otherwise kernel will see it.等于aggr_fault_handler
1331  如果 Called after addr is executed, unless... 且非Has this kprobe gone ? 则 Called after addr is executed, unless... 等于aggr_post_handler
1334  初始化链表头
1335  INIT_HLIST_NODE( & hlist)
1337  添加RCU保护项
1338  rcu新旧更换
