💅 raw_atomic_long_inc_and_test — Kernel API Manual ✨

okay so bestie, welcome to the raw_atomic_long_inc_and_test(9) page 💖 this is a raw atomic long situation and honestly? she's iconic. full manual name is Kernel API Manual, so you know she's official 👑

🌸 NAME 🌸

raw_atomic_long_inc_and_test — atomic increment and test if zero with full ordering ⭐

🦋 SYNOPSIS 🦋

bool raw_atomic_long_inc_and_test (atomic_long_t *v );

🎀 ARGUMENTS 🎀

  • v — pointer to atomic_long_t 💫 that's your girl, the thing getting incremented

✨ DESCRIPTION ✨

so what she does is: atomically updates v to (v + 1) with full ordering 🔥 like, all at once, no half-steps, no tea no shade. atomically. periodt.

also she's safe to use in noinstr code 🧚 which lowkey is her whole personality. but bestie, hear me — prefer atomic_long_inc_and_test elsewhere 🙈 this raw version is for the special noinstr situations, not your everyday vibe.

👑 RETURN 👑

returns true if the resulting value of v is zero, false otherwise 💀 simple as that, no cap.

🌈 SEE ALSO 🌈

first up, the kernel file she lives in — go say hi 🫶

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

and now the entire extended universe, aka the whole atomic_long family, in order, no skips, fr fr 🍓:

and that's the whole page bestie, you ate 💅✨ mwah 🫶

this came from ./include/linux/atomic, dated October 2026, and it's filed under raw_atomic_l...inc_and_test(9) — go forth and increment responsibly 😭💖
