raw_atomic_..._and_acquire(9)

💅 raw_atomic_..._and_acquire(9) — Kernel API Manual ✨

🎀 NAME 🎀

raw_atomic_long_fetch_and_acquire — atomic bitwise AND with acquire ordering. Slay. 💅

✨ SYNOPSIS ✨

long raw_atomic_long_fetch_and_acquire (long i , atomic_long_t *v );

🫶 ARGUMENTS 🫶

• i — a long value. Bestie, it's the thing getting AND-ed in.
• v — pointer to atomic_long_t. This is the atomic long being updated.

💖 DESCRIPTION 💖

Okay so literally: this atomically updates v to (v & i) with acquire ordering. No cap, that's the whole vibe. 🌸

It's safe to use in noinstr code; prefer atomic_long_fetch_and_acquire elsewhere. 👑

⭐ RETURN ⭐

The original value of v. Like, the value it had before the AND happened. Iconic. 🫶
