debug_rt_mutex

Name: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.

Proto:void debug_rt_mutex_deadlock(enum rtmutex_chainwalk chwalk, struct rt_mutex_waiter *act_waiter, struct rt_mutex *lock)

Type:void

Parameter:

Type	Parameter	Name
enum rtmutex_chainwalk	chwalk
struct rt_mutex_waiter *	act_waiter
struct rt_mutex *	lock

If Not 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 || chwalk == Invoke deadlock detection with a full || Not act_waiter Then Return

task = rt_mutex_owner(lock)

If task && task != current process Then

deadlock_task_pid = get_pid(task_pid(task))

deadlock_lock = lock
