💅 atomic_long_...turn_release(9) — from the Kernel API Manual ✨

okay so bestie, we're in the Kernel API Manual today and the page we're reading is atomic_long_...turn_release(9) (yes the name is literally truncated with dots, that's just how it's filed, don't come for me 🫶). Sit down, hydrate, and let's get into it.

🌸 NAME 🌸

atomic_long_inc_return_release — atomic increment, but make it release-ordered 💅

✨ SYNOPSIS ✨

long atomic_long_inc_return_release (atomic_long_t *v );

🎀 ARGUMENTS 🎀

  • v — pointer to atomic_long_t. that's the whole vibe. it's the thing you're incrementing, bestie.

🦋 DESCRIPTION 🦋

So what does this icon actually do? It atomically updates v to (v + 1) with release ordering. like, the whole update happens as one indivisible little moment, no one else can catch it mid-step, and the release ordering is doing its memory-barrier thing so everything you wrote before this stays put before it. slay. 🔥

⚠️ Heads up: this is unsafe to use in noinstr code. Instead use raw_atomic_long_inc_return_release there. no cap, that's the rule — don't be the main character who ignores it 😭

👑 RETURN 👑

It hands you back the updated value of v. So you know exactly what it landed on. iconic behaviour honestly.

🌈 SEE ALSO 🌈

okay this section is long, like the group chat after a full moon long, so buckle up 💀. The kernel file for all of this is ./include/linux/atomic/atomic-instrumented.h 🍓
