nfsd4_put_client(9)

💅 nfsd4_put_client(9) — aka the Kernel API Manual glow-up 🎀

okay so bestie, welcome to nfsd4_put_client(9) ✨ this is the Kernel API Manual entry and honestly it's short and sweet and I'm obsessed with how much it does with so little.

---

✨ NAME ✨

nfsd4_put_client — release a reference on an nfs4_client 🫶

like, you're putting the client down. gently. because you're a responsible main character.

---

🌸 SYNOPSIS 🌸

void nfsd4_put_client (struct nfs4_client *clp );

that's it. that's the whole vibe check. no return value, no drama, void and done 💀

---

🦋 ARGUMENTS 🦋

• clp — the client to be released 💖 this is the one you're letting go of, bestie. hand it over and let the kernel handle the rest.

---

💜 DESCRIPTION 💜

okay so here's the tea ☕ — when the last reference is released, the client is freed. no cap, that's the whole mechanic.

like it's giving refcount energy fr fr 🔥 you drop your reference, and if you were the last one holding on? boom, the client gets freed. last one out, lights off, iconic behavior 👑

ngl bestie, the refcount rule is the whole plot — only the last release frees the client. don't be out here thinking every nfsd4_put_client call is the finale 😭
