lockref_get(9)

💅 lockref_get(9) — Kernel API Manual, bestie edition

okay so this is a page from the Kernel API Manual, and honestly? it's a short one, so we can absolutely get through it together. grab your iced coffee 🍓

---

✨ NAME ✨

lockref_get — increments the reference count unconditionally. no vibe check, no nothing, it just goes 📈

---

🌸 SYNOPSIS 🌸

void lockref_get (struct lockref *lockref );

that's it. that's the whole signature. she's simple, she's iconic 👑

---

🎀 ARGUMENTS 🎀

• lockref — pointer to a lockref structure 🫶 literally just a pointer to the thing, bestie

---

🦋 DESCRIPTION 🦋

so here's the tea ☕ — this operation is only valid if you already hold a reference to the object. like, you already have one, so you know the count can't be zero. no cap. if you don't already hold a reference, this is not the function for you, and that's on periodt 💀

it bumps the count unconditionally — no checks, no guardrails, no "not me checking first" energy. the safety here comes from you, the caller, already having that reference in your hand. main character responsibility right there 💅
