raw_atomic_l...h_or_relaxed(9)

okay so bestie, this is raw_atomic_l...h_or_relaxed(9) from the Kernel API Manual, and it is giving atomic bitwise OR with relaxed ordering ✨💅

🎀 NAME 🎀

raw_atomic_long_fetch_or_relaxed — atomic bitwise OR with relaxed ordering 🫶

✨ SYNOPSIS ✨

long raw_atomic_long_fetch_or_relaxed (long i , atomic_long_t *v );

🦋 ARGUMENTS 🦋

• i — a long value 💖
• v — pointer to atomic_long_t 🎀

🌸 DESCRIPTION 🌸

Okay so this atomically updates v to (v | i) with relaxed ordering. That's the whole move, and it ate 💅✨

Safe to use in noinstr code; prefer atomic_long_fetch_or_relaxed elsewhere. Not me dropping the important note right here, but yes bestie, remember it 🫶

👑 RETURN 👑

The original value of v. So you get the old value back, iconic behavior fr fr 💖
