/*
* This is a very simple lock trace implementation. It can be used to verify that the runtime is
* correctly following all locking rules.
*
* To log more kind of locks just do the following:
* - add an entry into the RuntimeLocks enum
- * - change mono_mutex_lock(mutex) to mono_locks_acquire (mutex, LockName)
- * - change mono_mutex_unlock to mono_locks_release (mutex, LockName)
+ * - change mono_os_mutex_lock(mutex) to mono_locks_os_acquire (mutex, LockName)
+ * - change mono_os_mutex_unlock(mutex) to mono_locks_os_release (mutex, LockName)
+ * - change mono_coop_mutex_lock(mutex) to mono_locks_coop_acquire (mutex, LockName)
+ * - change mono_coop_mutex_unlock(mutex) to mono_locks_coop_release (mutex, LockName)
* - change the decoder to understand the new lock kind.
