raw_atomic64_fetch_andnot(9)

💖 raw_atomic64_fetch_andnot(9) 💖

okay bestie, this one's from the Kernel API Manual and it's called raw_atomic64_fetch_andnot — literally the atomic bitwise AND NOT with full ordering page. 💅 No cap, it's a whole vibe.

🎀 NAME 🎀

raw_atomic64_fetch_andnot — atomic bitwise AND NOT with full ordering.

✨ SYNOPSIS ✨

s64 raw_atomic64_fetch_andnot (s64 i , atomic64_t *v );

🦋 ARGUMENTS 🦋

• i — s64 value.
• v — pointer to atomic64_t.

🌸 DESCRIPTION 🌸

So the tea is: this atomically updates v to (v & ~i) with full ordering. That's the move. It's giving "bitwise AND NOT but make it atomic and fully ordered." ✨

It's safe to use in noinstr code; prefer atomic64_fetch_andnot elsewhere. That part matters, bestie.

🔥 RETURN 🔥

The original value of v. Like, the before pic. The pre-update value. 💅
