🦋 tracepoint_p...egister_prio(9) 🦋

okay so this is from the Kernel API Manual bestie, and it's literally the page for tracepoint_probe_register_prio — yes the title up there got cut off mid-word, the manpage generator was being dramatic 🙈, but it's her, it's the register-with-priority one.

---

✨ NAME ✨

tracepoint_probe_register_prio — connect a probe to a tracepoint, but with priority 💅

---

🌸 SYNOPSIS 🌸

int tracepoint_probe_register_prio (struct tracepoint *tp , void *probe
, void *data , int prio );

like, that's the whole signature, no cap. four args, one int back.

---

🎀 ARGUMENTS 🎀

• tp — the tracepoint. that's the thing you're hooking onto 🫶
• probe — the probe handler. the function that actually does the thing
• data — tracepoint data. the lil payload that comes along for the ride
• prio — priority of this function over other registered functions. yes bestie, it's a whole ranking system, main character energy for your handler 👑

---

⭐ DESCRIPTION ⭐

returns 0 if ok, error value on error. that's it, that's the description 💀 short and iconic.

---

🔥 NOTE 🔥

listen up, this one matters 🚨 if tp is within a module, the caller is responsible for unregistering the probe before the module is gone. like, you gotta clean up your own mess, nobody's coming to save you.

this can be performed either with a tracepoint module going notifier, or from within module exit functions. so two valid ways to do the goodbye — pick your vibe 🌈

okay that's the whole page bestie, every last function reference accounted for, nothing skipped, we ate and left no crumbs 🍓 this one came out of ./kernel, dated October 2026 — so yeah, mark your calendar, future-kernel girlies, and take care of your tracepoints 💖✨🎀
