💅 cpu_rmap_get(9) — like, the Kernel API Manual page you didn't know you needed

okay so bestie, welcome to the cpu_rmap_get(9) glow-up ✨ this little icon lives in the Kernel API Manual and honestly? she's a tiny one but she MATTERS, so let's get into it 🎀

✨ NAME ✨

cpu_rmap_get — internal helper to get new ref on a cpu_rmap 💖

like, she's the friend who bumps your refcount when you need a hand. internal-only, so don't go thinking she's your main character — she's supporting cast, but she ate 🫶

🌸 SYNOPSIS 🌸

void cpu_rmap_get (struct cpu_rmap *rmap );

that's it. that's the whole thing. no cap, she's a one-liner 😭 returns void, so don't be out here looking for a return value, she gives you nothing back and she's iconic for it 💅

🦋 ARGUMENTS 🦋

  • rmap — the reverse-map, allocated with alloc_cpu_rmap ✨ so like, this is a struct cpu_rmap * that you (or a friend) already got from alloc_cpu_rmap, and now you're asking for a fresh ref on it. don't just pass her any random pointer, bestie, she has to come from there 😤

👑 SEE ALSO 👑

ok so this is the part where I introduce you to the whole friend group, they all hang out and honestly they're all essential, so don't skip the roll call 🧚

Kernel file ./lib/cpu_rmap.c — that's the whole squad's address, literally the file to go read 📖

like, go read them, iykyk 🔥

fr fr reminder: cpu_rmap_get is described as an internal helper — so treat her accordingly, she's not the front-door API vibe 🌈

and that's the page, bestie, you're all caught up 🍓 this little gem lives in ./lib and the version/date stamp on it is October 2026 — cpu_rmap_get(9), mwah, love that for us 💜🎀🦋
