函数名称：Unoptimize a kprobe if p is optimized

函数原型：static void unoptimize_kprobe(struct kprobe *p, bool force)

返回类型：void

参数：

类型参数名称
struct kprobe *p
boolforce
680  如果非Return true if the kprobe is an aggregator 或Return true(!0) if the kprobe is disarmed. Note: p must be on hash list 则返回
683  op等于container_of - cast a member of a structure out to the containing structure*@ptr: the pointer to the member.*@type: the type of the container struct this is embedded in.*@member: the name of the member within the struct.(p, structoptimized_kprobe, kp)
684  如果非Is this kprobe really running optimized path ? 则返回
687  如果非链表为空则
688  如果optprobe_queued_unopt(op)则
690  如果force则
698  否则
700  删除链表项并重新初始化
701  * Indicates various status flags. * Protected by kprobe_mutex after this kprobe is registered.与等于probe is really optimized.* NOTE:* this flag is only for optimized_kprobe.的反
703  返回
707  如果force则
709  Short cut to direct unoptimizing
710  否则
711  添加链表项
712  Start optimizer after OPTIMIZE_DELAY passed
