raw_atomic_f..._xor_release(9)

🧚 raw_atomic_f..._xor_release(9) 🧚

okay bestie, welcome to the Kernel API Manual — this is the page for raw_atomic_f..._xor_release(9), and it is giving atomic bitwise XOR with release ordering. 💅✨

🌸 NAME 🌸

raw_atomic_fetch_xor_release — atomic bitwise XOR with release ordering. That's the whole name-vibe: atomic, XOR, release. periodt. 💖

✨ SYNOPSIS ✨

The signature is literally this, bestie — spaces and all:

int raw_atomic_fetch_xor_release (int i , atomic_t *v );

💖 ARGUMENTS 💖

• i — an int value. that's it, just an int, no cap. 🫶
• v — pointer to atomic_t. this is the atomic cutie getting XORed. 🎀

🌸 DESCRIPTION 🌸

Atomically updates v to (v ^ i) with release ordering. so it does the XOR and the release ordering in one atomic slay. ✨🔥

Safe to use in noinstr code; prefer atomic_fetch_xor_release elsewhere. so yes, it's safe in noinstr code, but outside that zone the preferred one is atomic_fetch_xor_release — noted, bestie. 🫶💅

🦋 RETURN 🦋

The original value of v. not the new one, not a vibe-check result — the original value. 😭💖

💅 SEE ALSO 💅
