* - triggers_ht:
- * associates a condition to a struct lttng_trigger_ht_element.
+ * associates a trigger to a struct lttng_trigger_ht_element.
* The hash table holds the ownership of the
* lttng_trigger_ht_elements along with the triggers themselves.
+ * - triggers_by_name_uid_ht:
+ * associates a trigger (name, uid) tuple to
+ * a struct lttng_trigger_ht_element.

+ * for lookup on registration.
*
* The thread reacts to the following internal events:
* 1) creation of a tracing channel,
* notification_trigger_clients_ht,
* - add trigger to channel_triggers_ht (if applicable),
* - add trigger to session_triggers_ht (if applicable),
+ * - add trigger to triggers_by_name_uid_ht
* - add trigger to triggers_ht
* - evaluate the trigger's condition right away to react if that condition
* is true from the beginning.
* - remove the trigger from the notification_trigger_clients_ht,
* - remove trigger from channel_triggers_ht (if applicable),
* - remove trigger from session_triggers_ht (if applicable),
+ * - remove trigger from triggers_by_name_uid_ht
* - remove trigger from triggers_ht
*
* 5) Reception of a channel monitor sample from the consumer daemon
