relay_remove_buf(9)

relay_remove_buf(9) 💅

okay so this is the Kernel API Manual page for relay_remove_buf(9), and bestie, it’s literally the cleanup era for a channel buffer ✨

---

💖 NAME 💖

relay_remove_buf — remove a channel buffer. That’s the whole name, and it ate, no cap 🎀

---

🛠️ SYNOPSIS 🛠️

the signature, verbatim, because we do not mess with code here:

void relay_remove_buf (struct kref *kref );

---

🫶 ARGUMENTS 🫶

• kref — the target kernel reference that contains the relay buffer. like, it’s the reference wrapper holding your buffer, bestie 🦋

---

🌸 DESCRIPTION 🌸

okay so what this function does is removes the file from the filesystem, and that also frees the rchan_buf_struct and the channel buffer. it’s giving “clean up your room and take the whole vibe with you” 💅

important caveat, fr fr: it should only be called from kref_put. that’s the rule, and we respect the rule 😭
