函数名称：unoptimize_all_kprobes

函数原型：static void unoptimize_all_kprobes(void)

返回类型：void

参数：无

868  mutex_lock( & This protects kprobe_table and optimizing_list )
870  如果非NOTE: change this value only with kprobe_mutex held 则
871  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.
872  返回
875  cpus_read_lock()
876  NOTE: change this value only with kprobe_mutex held = false
877  以i小于KPROBE_TABLE_SIZE循环
878  head等于kprobe_table[i]
880  如果非Is this kprobe disabled ? 则Unoptimize a kprobe if p is optimized
884  cpus_read_unlock()
885  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.
888  Wait for completing optimization and unoptimization
889  printk - print a kernel message*@fmt: format string* This is printk(). It can be called from any context. We want it to work.* We try to grab the console_lock. If we succeed, it's easy - we log the* output and call the console drivers
