__atomic_add_ifless(9)

📦 version 7.3.1, in nixpkgs unstable

🌸 __atomic_add_ifless (9) — kernel API manual, bestie edition 🌸

okay so quick vibe check: this is the __atomic_add_ifless(9) page from the kernel API manual. yes it's a real one. yes it's niche. and yes, we're gonna get through it together 💖

✨ NAME ✨

__atomic_add_ifless — add if the result is less than a given value.

like, conditional addition. it only commits the add when the outcome passes the vibe check 💅

✨ SYNOPSIS ✨

bool __atomic_add_ifless (atomic_t *v , int a , int u );

she returns a bool. noted. 🎀

✨ ARGUMENTS ✨

  • v — pointer of type atomic_t. this is the thing we're adding to, bestie 🫶
  • a — the amount to add to v...
  • u — ...if (v + a) is less than u.

ok the way those last two args literally finish each other's sentences?? that's the whole gag, no cap 😭 it's giving "one thought split across two arguments."

✨ DESCRIPTION ✨

returns true if (v + a) was less than u, and false otherwise.

that's it. that's the function. tiny, iconic, does exactly one job 👑

ngl, the naming is doing a lot of heavy lifting here — read it as "atomic add, if less" and you're basically already a kernel dev 💀

✨ SEE ALSO ✨

ok buckle up bestie, this list is long — but every single one of these is real and lives in the same little corner of the kernel 🌈

like, the bnx2x crew really said "we're all showing up to this page" and honestly? respect 😤💜

🎀 cute lil sign-off 🎀

this page ships out of ./drivers/net/ethernet/broadco... and it's dated October 2026 — so yeah, she's a keeper from the future-ish. go read the kernel file, hydrate, and remember: add only if less. periodt 💅✨🦋
