clear_event_triggers(9)

💖 NAME 💖

okay so bestie, clear_event_triggers — from the Kernel API Manual, section 9 — is literally here to clear all triggers associated with a trace array. That’s the whole NAME moment. Periodt. 💅

---

✨ SYNOPSIS ✨

the signature is giving exactly this, no notes:

void clear_event_triggers (struct trace_array *tr );

---

🎀 ARGUMENTS 🎀

• tr — the trace array to clear. That’s it, that’s the argument, bestie.

---

🦋 DESCRIPTION 🦋

okay so here’s the tea: for each trigger, the triggering event has its tm_ref decremented via trace_event_trigger_enable_disable, and any associated event (in the case of enable/disable_event triggers) will have its sm_ref decremented via free->trace_event_enable_disable. That combination effectively reverses the soft-mode/trigger state added by trigger registration.

🚨 Technical caveat, no cap: clear_event_triggers must be called with event_mutex held. Like, that’s not a suggestion, bestie. 🔥
