raw_atomic_long_dec_return(9)

✨ NAME ✨

Okay bestie, meet raw_atomic_long_dec_return from the Kernel API Manual 🌸 — the atomic decrement with full ordering that hands you back the updated value. Lowkey iconic. 💅

---

🎀 SYNOPSIS 🎀

long raw_atomic_long_dec_return (atomic_long_t *v );

---

🦋 ARGUMENTS 🦋

• v — pointer to atomic_long_t 🫶

---

💖 DESCRIPTION 💖

Atomically updates v to (v - 1) with full ordering. ✨

Safe to use in noinstr code; prefer atomic_long_dec_return elsewhere, bestie. 🌈

---

👑 RETURN 👑

The updated value of v — yes, it gives you the new number back, periodt. 💅
