debug_rt_mutex

函数名称：We fill out the fields in the waiter to store the information about* the deadlock. We print when we return. act_waiter can be NULL in* case of a remove waiter operation.

函数原型：void debug_rt_mutex_deadlock(enum rtmutex_chainwalk chwalk, struct rt_mutex_waiter *act_waiter, struct rt_mutex *lock)

返回类型：void

参数：

类型	参数	名称
enum rtmutex_chainwalk	chwalk
struct rt_mutex_waiter *	act_waiter
struct rt_mutex *	lock

如果非We want to turn all lock-debugging facilities on/off at once,* via a global flag. The reason is that once a single bug has been* detected and reported, there might be cascade of followup bugs* that would just muddy the log. So we report the first one and或chwalk恒等于 Invoke deadlock detection with a full或非act_waiter则返回

task等于rt_mutex_owner(lock)

如果task且task不等于当前进程则

deadlock_task_pid等于get_pid(task_pid(task))

deadlock_lock等于lock
