💖 t_show_filters(9) — Kernel API Manual 💖

okay bestie, welcome to the t_show_filters(9) page — it's the seq_file callback that shows off your active event filters, and it's literally giving useful kernel energy. ✨

✨ NAME ✨

t_show_filters — seq_file callback to display active event filters 🎀

---

🦋 SYNOPSIS 🦋

int t_show_filters (struct seq_file *m , void *v );

---

🎀 ARGUMENTS 🎀

• m — the seq_file interface for formatted output. It's the main character handling the pretty printing. 💅
• v — the current trace_event_file being iterated. That's the event file currently getting its moment in the spotlight. 👑

---

💅 DESCRIPTION 💅

okay so this callback identifies and prints the active filters for the current event file in the iteration. If a filter is applied to the current event — and yes, if so — it prints the system name, event name, and the filter string. no cap, that's the whole vibe. 🦋
