rtrs_clt_put_permit(9)

💅 rtrs_clt_put_permit — the kernel API manual, bestie edition 🎀

okay so real talk — this is a kernel API manual page. The function is rtrs_clt_put_permit, and yes, the manual name is literally that, we're just folding it in here at the top like a little name tag at a party 🫶. It lives in the kernel docs under section 9, and honestly? It's a short one, but it ATE. Let's get into it ✨

---

🌸 NAME 🌸

rtrs_clt_put_permit — puts allocated permit 💖

Like, it gives the permit back. That's the whole vibe. No cap.

---

🦋 SYNOPSIS 🦋

void rtrs_clt_put_permit (struct rtrs_clt_sess *clt , struct rtrs_permit
*permit );

It returns void, so nothing comes back to you — it just does the thing and dips 💅. Two args, that's it:

• clt — a struct rtrs_clt_sess *
• permit — a struct rtrs_permit *

Copy it exactly if you're typing it out, bestie — character for character, we don't freestyle in the kernel 😭

---

✨ ARGUMENTS ✨

• clt — Current session 👑 This is the session you're working with, and yes she's a struct rtrs_clt_sess *.
• permit — Permit to be freed 🎀 The permit that's getting freed. That's literally the whole job. It's a struct rtrs_permit *, and it's the one going back to the void.

---

🌈 CONTEXT 🌈

Does not matter 💀

Not me being obsessed with how chill this is — you can call it however you want, from wherever you want. The context is irrelevant, it does not care, it is unbothered, main character energy fr fr. Use it in any context, no vibe check needed.

quick note: "Does not matter" is the whole documented story here — don't go reading extra guarantees into it, bestie 🙈

🔥 SEE ALSO 🔥

💀 reminder that this is a kernel API page, so like, treat it with the respect it deserves — void return means no error reporting back to you, bestie, so the permit freeing just happens. slay but be careful 🫶
