relay_destroy_channel(9)

💖 relay_destroy_channel(9) — the kernel API manual, but make it cute 🎀

okay so bestie, welcome to the Kernel API Manual entry for relay_destroy_channel(9) — yes the (9) is giving "section 9, kernel developer era" and honestly? iconic. this is the whole page, no skips, no cuts, we're doing the full read 🫶

✨ NAME ✨

relay_destroy_channel — literally just frees the channel struct. that's the whole vibe. one job, does it, periodt 💅

---

🦋 SYNOPSIS 🦋

void relay_destroy_channel (struct kref *kref );

like yes, that's the entire signature. void return because it doesn't report back to you, it just does the thing and dips 😌

---

🌸 ARGUMENTS 🌸

• kref — the target kernel reference that contains the relay channel 💖 this is the struct you're handing over, and it's the kernel reference wrapping your relay channel, so like… know which one you're passing, okay? 🙈

👑 DESCRIPTION 👑

okay so here's the tea: relay_destroy_channel frees the channel struct. that's it, that's the function.

but — and this is the important part, bestie — it should only be called from kref_put. not "you could also call it from here," not "maybe from there," no. only from kref_put. this is not a suggestion, this is the rule 🌈

💀 fr fr do not go calling this from random places, the manpage said only from kref_put and we respect the manpage in this house
