💅 event_trigger_unlock_commit(9) — the Kernel API Manual, bestie edition

okay so you found your way to event_trigger_unlock_commit(9) in the Kernel API Manual and honestly? welcome, you're gonna do great ✨ this one's a little helper with a lot of opinions.

---

🌸 NAME

event_trigger_unlock_commit — handles triggers and finishes up the event commit. two jobs, one function, main character energy fr fr 👑

---

🎀 SYNOPSIS

void event_trigger_unlock_commit (struct trace_event_file *file , struct
trace_buffer *buffer , struct ring_buffer_event *event , void *entry ,
unsigned int trace_ctx );

that's the whole signature, copy it exactly, don't get creative with it 💖

---

🦋 ARGUMENTS

• file — the file pointer that's hanging out with this event. it's the event's plus-one 🫶
• buffer — the ring buffer the event is being written to. that's where the event lives, that's its whole vibe.
• event — the event's meta data sitting in the ring buffer. not the event itself, just the ~metadata~ of it 🙈
• entry — the actual event itself. the real one. the main character. ✨
• trace_ctx — the tracing context flags. little flags, big job.

---

⭐ DESCRIPTION

so this is a helper function (a lil sidekick, we love a supportive bestie) for handling triggers that need data from the event itself. it also does a vibe check on the event against filters — and if the event is soft disabled and should be discarded, it gets discarded. no cap. 🗑️

basically: handle the trigger, test the filters, yeet the ones that don't belong. iconic behavior honestly.
