raw_atomic_and(9)

🌸 NAME 🌸

okay bestie, meet raw_atomic_and(9) from the Kernel API Manual 💖 she's the atomic bitwise AND with relaxed ordering — literally the calm little atomic bitwise queen of atomic_t. no cap.

✨ SYNOPSIS ✨

void raw_atomic_and (int i , atomic_t *v );

💅 ARGUMENTS 💅

• i — int value. that's the AND-ing friend, periodt.
• v — pointer to atomic_t. this is the atomic bestie getting updated.

🌸 DESCRIPTION 🌸

she atomically updates v to (v & i) with relaxed ordering — that's the whole vibe, and it's giving atomic bitwise AND. 🔥

also: she's safe to use in noinstr code — but bestie, prefer atomic_and elsewhere. iykyk 💅

🦋 RETURN 🦋

Nothing. not a crumb. literally Nothing. 😌
