nft_unregister_expr(9)

🦋 nft_unregister_expr ✨

okay bestie, so this is a page from the Kernel API Manual — yes, that manual — and it's about nft_unregister_expr, the little function that says "bye bye" to an expr type. group-chat-level simple, i promise 🫶

---

💅 NAME 💅

nft_unregister_expr — unregister nf_tables expr type. that's it, that's the whole vibe. it's the *un*register, the reverse main character move 🔥

---

✨ SYNOPSIS ✨

void nft_unregister_expr (struct nft_expr_type *type );

literally one function, one argument, one void return — no drama, no return value, just pure "i'm out" energy 💅

---

🎀 ARGUMENTS 🎀

• type — the expr type. that's the thing you're unregistering, bestie. hand it over and it's donezo 🦋

---

🌸 DESCRIPTION 🌸

so basically, nft_unregister_expr unregisters the expr type for use with nf_tables. that's the whole thing!

think of it like leaving the group chat 👋 — the expr type was registered, it was living its nf_tables life, and now it's being unregistered. it's giving graceful exit. no cap, that is genuinely all this function does.
