raw_atomic_read(9)

💖 raw_atomic_read(9) 💖

okay bestie, welcome to the Kernel API Manual page for raw_atomic_read(9) — yes, the manual name is folded in right here at the top, because we are doing this cute style. This is the atomic load with relaxed ordering moment. ✨

---

🌸 NAME 🌸

raw_atomic_read — atomic load with relaxed ordering. 🫶

---

✨ SYNOPSIS ✨

int raw_atomic_read (const atomic_t *v );

---

🎀 ARGUMENTS 🎀

• v — pointer to atomic_t. That's the thing you're pointing at, bestie. 💅

---

🦋 DESCRIPTION 🦋

Atomically loads the value of v with relaxed ordering. It's giving “load the atomic, but relaxed.” 😌

Safe to use in noinstr code; prefer atomic_read elsewhere. 🫡

So yes: noinstr? Safe, bestie. Everywhere else? Prefer atomic_read. Noted. 💖

---

⭐ RETURN ⭐

The value loaded from v. That's it, that's the return. 🎀

okay that's the whole page, bestie. The footer energy is source/version ./include/linux/atomic and date October 2026. Mwah 💋
