raw_atomic_l...turn_release(9)

✨ raw_atomic_l...turn_release(9) ✨

okay so bestie, we're deep in the Kernel API Manual and today's main character is a tiny atomic function with serious release-ordering energy 💅 don't let the truncated title scare you — she's iconic, she's specific, and she's literally right here.

---

💖 NAME 💖

raw_atomic_long_add_return_release — atomic add with release ordering 🎀

---

🌸 SYNOPSIS 🌸

long raw_atomic_long_add_return_release (long i , atomic_long_t *v );

---

🦋 ARGUMENTS 🦋

• i — the long value you're adding, bestie. that's the whole assignment 💖
• v — a pointer to atomic_long_t, aka the thing getting updated ✨

---

🔥 DESCRIPTION 🔥

So the vibe is: this atomically updates v to (v + i) with release ordering. no cap, that's the entire glow-up 💫

She is safe to use in noinstr code — yes, that noinstr — but outside of that, prefer atomic_long_add_return_release instead. like, she's the raw special-case queen, not the everyday default 👑

---

👑 RETURN 👑

You get back the updated value of v. that's it, that's the tea 🍓
