raw_atomic_..._inc_release(9)

📦 version 7.3.1, in nixpkgs unstable

okay bestie, this is the Kernel API Manual page for raw_atomic_..._inc_release(9) — yes, the title is dramatic with those ellipses, but the actual star is raw_atomic_long_fetch_inc_release, and she is giving atomic increment with release ordering ✨

✨ NAME ✨

  • raw_atomic_long_fetch_inc_release — atomic increment with release ordering 💫

🌸 SYNOPSIS 🌸

the signature, literally:

long raw_atomic_long_fetch_inc_release (atomic_long_t *v );

🎀 ARGUMENTS 🎀

  • v — pointer to atomic_long_t 🫶

💅 DESCRIPTION 💅

okay so what it does: it atomically updates v to (v + 1) with release ordering. the “atomically” is not decorative, bestie — it is the whole point 🔥

it is safe to use in noinstr code; anywhere else, prefer atomic_long_fetch_inc_release — that is the “please use this one in normal life” option 💖

🦋 RETURN 🦋

it returns the original value of v — the before picture, not the incremented after. so if you were expecting the new value, no bestie, that is not this function 📸

🌈 SEE ALSO 🌈

the whole atomic-long friend group, plus the kernel file:

and that is the page, bestie 🫶 — source path ./include/linux/atomic, date October 2026, manual raw_atomic_..._inc_release(9); now go be atomic and release-ordered responsibly 💅✨
