atomic_fetch_andnot_acquire(9)

okay bestie, welcome to atomic_fetch_andnot_acquire(9) from the Kernel API Manual 💅 this one is giving atomic bitwise AND NOT with acquire ordering, and yes it ate.

💖 NAME 💖

atomic_fetch_andnot_acquire — atomic bitwise AND NOT with acquire ordering.

🌸 SYNOPSIS 🌸

int atomic_fetch_andnot_acquire (int i , atomic_t *v );

🎀 ARGUMENTS 🎀

• i — an int value.
• v — pointer to atomic_t.

✨ DESCRIPTION ✨

okay so picture this: this function atomically updates v to (v & ~i) with acquire ordering. that's the whole vibe, and it's lowkey iconic ✨

⚠️ Unsafe to use in noinstr code 💀 use raw_atomic_fetch_andnot_acquire there instead. no cap, that's the rule.

🦋 RETURN 🦋

You get the original value of v back. that's it, that's the tea ☕

🌈 SEE ALSO 🌈
