raw_atomic_long_inc(9)

📦 version 7.3.1, in nixpkgs unstable

🌸 raw_atomic_long_inc — the manual, but make it make sense 🌸

okay so bestie, this page lives in the Kernel API Manual and honestly it's a short one, but it's lowkey iconic. we're doing one (1) thing here: bumping an atomic_long_t up by one, atomically. that's the whole vibe.

✨ NAME ✨

raw_atomic_long_inc — an atomic increment, but make it relaxed ordering 💅

✨ SYNOPSIS ✨

void raw_atomic_long_inc (atomic_long_t *v );

✨ ARGUMENTS ✨

  • v — pointer to atomic_long_t. that's it. that's the argument. she's a pointer and she knows it 🎀

✨ DESCRIPTION ✨

So here's the tea, bestie: it atomically updates v to (v + 1) with relaxed ordering. atomically means nobody's gonna catch it mid-bump, fr fr — the whole thing happens as one indivisible little moment. and relaxed ordering means we're not doing any extra memory-barrier choreography, we're just out here vibing 😌✨

It's safe to use in noinstr code — highkey important, that's the whole reason this raw version exists. but everywhere else? prefer atomic_long_inc. like, atomic_long_inc is the main character for general use; this one is the backstage-pass version for the special noinstr situations 🎟️

ngl, if you're not in noinstr code, just use atomic_long_inc. it's giving "use the normal one" energy. this page said it itself, so don't come for me 💀

✨ RETURN ✨

Nothing. Not zero, not void-as-a-joke — genuinely nothing. she does her little increment and leaves. no receipts, no notes, no return value 🫶

✨ SEE ALSO ✨

the whole atomic-long family reunion is right here — every single one of them, and yes I'm listing every single one, we do not skip entries in this house 👑

first up, the kernel file where all this magic lives:

  • Kernel file ./include/linux/atomic/atomic-long.h 🦋

and now the extended fam:

okay that's the whole page, you ate that 💖 this lil artifact comes from ./include/linux/atomic (yes, that's the source path, she's lowkey humble about it) and the version stamps her as October 2026 — so go forth, increment responsibly, and remember: atomic_long_inc for the everyday, raw_atomic_long_inc when you're in noinstr and you mean it. periodt. ✨🎀💜
