raw_atomic64_andnot(9)

💅 raw_atomic64_andnot — Kernel API Manual ✨

okay so bestie, welcome to the raw_atomic64_andnot(9) page 🎀 this one lives in the Kernel API Manual, and it's giving "small but mighty" energy fr fr.

---

🌸 NAME 🌸

raw_atomic64_andnot — atomic bitwise AND NOT with relaxed ordering 💖

like... it does an AND NOT, and it does it atomically, and it's relaxed about the ordering. main character energy, no cap ✨

---

🦋 SYNOPSIS 🦋

void raw_atomic64_andnot (s64 i , atomic64_t *v );

literally the whole signature, character for character, because we do not play with code around here 💅

---

🍓 ARGUMENTS 🍓

• i — an s64 value 🫶 that's the thing getting AND-NOT-ed in.
• v — pointer to atomic64_t 💫 the lucky variable that gets updated.

---

🧚 DESCRIPTION 🧚

Atomically updates v to (v & ~i) with relaxed ordering. yep, that's the whole vibe — it takes v, does a bitwise AND with the complement of i, and writes it back, all without anyone else sneaking in mid-operation 😌✨

Safe to use in noinstr code 🫡 but outside of that, prefer atomic64_andnot elsewhere. like, raw_ is the special-occasion friend; atomic64_andnot is your everyday bestie 💖

---

⭐ RETURN ⭐

Nothing. 🫶 not void-ish nothing, literally nothing comes back. it just does the thing and leaves. iconic.
