raw_atomic_read_acquire(9)

💅 raw_atomic_read_acquire(9) — from the Kernel API Manual, bestie 💅

✨ NAME ✨

raw_atomic_read_acquire — it's an atomic load, but make it acquire ordering. No cap, that's literally the whole vibe.

---

🌸 SYNOPSIS 🌸

int raw_atomic_read_acquire (const atomic_t *v );

---

🎀 ARGUMENTS 🎀

• v — a pointer to an atomic_t. Like, the address of your atomic little bestie. Point at it and this function will read it. 😌

---

🦋 DESCRIPTION 🦋

Okay so it atomically loads the value of v with acquire ordering. That's the tea. ☕✨

It's safe to use in noinstr code — yes, that's a real thing, and it slays. But lowkey, prefer atomic_read_acquire everywhere else. This one is for when you're in the no-instrumentation zone, fr fr.

---

💖 RETURN 💖

You get the value that was loaded from v. That's it. That's the whole return. Go off. 👑
