atomic_long_...turn_release(9)

✨ NAME ✨

okay so bestie, welcome to the atomic_long_...turn_release(9) page from the Kernel API Manual 💖. The actual function is atomic_long_add_return_release — and it's literally atomic add with release ordering, periodt. No cap, that's the whole name.

---

🎀 SYNOPSIS 🎀

long atomic_long_add_return_release (long i , atomic_long_t *v );

---

🌸 ARGUMENTS 🌸

• i — a long value to add. Like, the amount you're dropping in 💅.
• v — pointer to atomic_long_t. The target of the whole operation 🎯.

---

🦋 DESCRIPTION 🦋

So here's the tea: it atomically updates v to (v + i) with release ordering. That's it, that's the function, slay ✨.

⚠️ But bestie, listen: it's unsafe to use in noinstr code. Use raw_atomic_long_add_return_release there instead. Don't forget, fr fr 😭.

---

👑 RETURN 👑

It hands you back the updated value of v — the new number after the add, iconic 💖.
