💅 nfsd4_run_cb(9) — a Kernel API Manual moment

okay so bestie, welcome to the nfsd4_run_cb(9) page ✨ this one lives in the Kernel API Manual, and it's genuinely short and sweet — like, blink and you'll miss it, but it still ate.

---

🎀 NAME 🎀

nfsd4_run_cb — queue up a callback job to run

like, literally just yeet a callback onto the queue so it can go do its little job 💅

---

✨ SYNOPSIS ✨

bool nfsd4_run_cb (struct nfsd4_callback *cb );

that's it. that's the whole signature. iconic behaviour honestly 🫶

---

🌸 ARGUMENTS 🌸

• cb — the callback to queue 👑 this is the little guy you're sending off to get queued up

---

🦋 DESCRIPTION 🦋

okay so here's the vibe: this function kicks off a callback to do its thing. that's the whole assignment. slay 💖

it returns false if it was already on a queue (like, been there, done that, no cap 🙈), and true otherwise. so the return value is basically a vibe check on whether your callback was already queued up or not ✨

ngl it's giving "small function, big responsibility". periodt.
