raw_atomic64_or(9)

💖 NAME 💖

raw_atomic64_or — atomic bitwise OR with relaxed ordering

Okay so this is raw_atomic64_or(9), straight from the Kernel API Manual, and it’s giving “tiny atomic helper with main character energy.” ✨

✨ SYNOPSIS ✨

void raw_atomic64_or (s64 i , atomic64_t *v );

🎀 ARGUMENTS 🎀

• i — an s64 value. That’s the thing getting OR’d in, bestie.
• v — pointer to atomic64_t. This is the atomic value being updated.

🌸 DESCRIPTION 🌸

Atomically updates v to (v | i) with relaxed ordering. No cap. 💅

Safe to use in noinstr code; prefer atomic64_or elsewhere. That’s the tea. 🫖

🦋 RETURN 🦋

Nothing. Not a value, not a status, literally nothing gets returned. 😭

Cute little sign-off, bestie: source/version is ./include/linux/atomic, date is October 2026, and this whole page is serving Kernel API Manual realness. 🎀✨
