函数名称：Return an optimized kprobe whose optimizing code replaces* instructions including addr (exclude breakpoint).

函数原型：static struct kprobe *get_optimized_kprobe(unsigned long addr)

返回类型：struct kprobe

参数：

类型参数名称
unsigned longaddr
442  struct kprobe * p = NULL
446  以非p且i小于MAX_OPTIMIZED_LENGTH循环p等于This routine is called either:* - under the kprobe_mutex - during kprobe_[un]register()* OR* - with preemption disabled - from arch/xxx/kernel/kprobes.c
449  如果p且Return true(!0) if the kprobe is ready for optimization. 则
