raw_atomic_..._xor_acquire(9)

raw_atomic_..._xor_acquire(9) 💅✨

okay so welcome to the Kernel API Manual, bestie — today’s main character is raw_atomic_long_fetch_xor_acquire, and she’s here to do an atomic bitwise XOR with acquire ordering. no cap, she’s iconic. 🦋

---

✨ NAME ✨

raw_atomic_long_fetch_xor_acquire — atomic bitwise XOR with acquire ordering. that’s the whole vibe, fr fr. 💖

📜 SYNOPSIS 📜

long raw_atomic_long_fetch_xor_acquire (long i , atomic_long_t *v );

🧾 ARGUMENTS 🧾

• i — a long value. that’s the value you’re XOR-ing in, bestie. 🌸
• v — pointer to atomic_long_t. that’s the atomic long getting updated. 💅

💖 DESCRIPTION 💖

okay so this one atomically updates v to (v ^ i) with acquire ordering. it’s giving “tiny but powerful,” and the way it does the whole thing atomically is lowkey iconic. ✨

it’s safe to use in noinstr code — but outside of that, please prefer atomic_long_fetch_xor_acquire elsewhere. iykyk. 🫶

🎁 RETURN 🎁

the original value of v. not the new one — the original one, bestie. that’s what you get back. 💖
