raw_atomic_..._add_release(9)

📦 version 7.3.1, in nixpkgs unstable

🌸 NAME 🌸

okay so bestie, this is the page for raw_atomic_..._add_release(9) in the Kernel API Manual — and the actual star of the show is raw_atomic_long_fetch_add_release: it's an atomic add with release ordering. Atomic girl summer, no cap 💅✨

🦋 SYNOPSIS 🦋

long raw_atomic_long_fetch_add_release (long i , atomic_long_t *v );

🎀 ARGUMENTS 🎀

  • i — a long value to add. That's literally the amount going in, bestie 💖
  • v — a pointer to atomic_long_t. This is the atomic long getting updated ✨

💜 DESCRIPTION 💜

Atomically updates v to (v + i) with release ordering. Like, the whole update happens atomically, and release ordering is doing its thing. That's the whole deal, periodt.

It's safe to use in noinstr code — yes, that's a real constraint, not a vibe. Everywhere else, prefer atomic_long_fetch_add_release — that's the instruction, bestie 🫶

⭐ RETURN ⭐

It hands back the original value of v — like, the value before the add happened. Not the new one. The original. 💅
