- * The caller retains the ownership of both the condition and action

+ * Prior to 2.13, the caller had to retain the ownership of both the condition
+ * and action. Both objects had to be kept alive for the lifetime of the trigger
+ * object. This is no longer the case as the condition and action objects are
+ * internally reference counted. It is safe to destroy a condition and an action
+ * after using them to create a trigger. However, they should no longer be used.
+ *
+ * If the action is a notification action with capture descriptors,
+ * the condition must be an event rule condition.
*
* A trigger must be registered in order to become activate and can
* be destroyed after its registration.
*
* Return 0 on success, a negative LTTng error code on error.
