mutex panic
Mutex could panic with below reasons:
1. bad mutex: It could happen with below context: mutex_enter, mutex_tryenter, mutex_destroy.
2. adaptive at high PIL
3. recursive mutex enter: If current thread tried to mutex_enter a lock which is held by itself, panic will happen.
4. not owner:It could happen with below context: mutex_destroy, mutex_exit
5. has waiters: It could happen with below context: mutex_destroy
Let's see above panic by examples from today.
