raw_atomic_inc_return(9)

💖 raw_atomic_inc_return(9) 💖

okay so welcome to the Kernel API Manual corner of the group chat 🫶. Today’s main character is raw_atomic_inc_return(9), and she’s giving atomic increment with full ordering and she’s not sorry. 💅

---

✨ NAME ✨

raw_atomic_inc_return — atomic increment with full ordering. No cap, that’s the whole vibe. 💖

---

📜 SYNOPSIS 📜

int raw_atomic_inc_return (atomic_t *v );

---

🫶 ARGUMENTS 🫶

• v — pointer to atomic_t. That’s it, bestie, just a lil pointer to the atomic thing. 🎀

---

💅 DESCRIPTION 💅

okay so this one is simple in the best way: it atomically updates v to (v + 1) with full ordering ✨. Yes bestie, full ordering, iconic behavior, we love to see it.

It’s safe to use in noinstr code; everywhere else, prefer atomic_inc_return, periodt. 🫶

---

🎁 RETURN 🎁

The updated value of v — that’s the fresh number after the +1, served with a little bow 🎀. Literally the post-increment glow-up. 💖
