raw_atomic64_xor(9)

📦 version 7.3.1, in nixpkgs unstable

🦋 NAME 🦋

okay so this is raw_atomic64_xor(9), straight outta the Kernel API Manual, and it does an atomic bitwise XOR with relaxed ordering 💅 that's the whole vibe.

✨ SYNOPSIS ✨

void raw_atomic64_xor (s64 i , atomic64_t *v );

like yes bestie, that's it, no cap 🫶

🎀 ARGUMENTS 🎀

  • i — an s64 value. that's the number you're XOR-ing in, periodt.
  • v — pointer to atomic64_t. the main character of this whole operation tbh 👑

💜 DESCRIPTION 💜

Atomically updates v to (v ^ i) with relaxed ordering ✨ the way that it just flips those bits in one go is genuinely iconic.

it's safe to use in noinstr code 😌 but the page says prefer atomic64_xor elsewhere — so like, use the raw one when you actually need it, iykyk 🔥

ngl, when the manpage says "prefer atomic64_xor elsewhere," it's being so fr. the raw_ version is the special-occasion shoe, not the everyday sneaker 👟

🌈 RETURN 🌈

Nothing. 🫥 literally zero. it hands you nothing back and honestly? that's its whole thing 💀

jealous? that's 80+ siblings and every single one is invited to the function 💀 iconic family, honestly 🎀

and that's the page, bestie 🌈💖 this whole thing came from the kernel file ./include/linux/atomic and it's dated October 2026 — so go forth and XOR atomically, you absolute legend 👑✨
