raw_atomic_l...tive_acquire(9)

📦 version 7.3.1, in nixpkgs unstable

💅 raw_atomic_l...tive_acquire(9) 💅

okay bestie, welcome to the Kernel API Manual ✨ (yes the title in the header is literally abbreviated like that, it's giving cryptic but we move — the real full name is in NAME, i promise)

🌸 NAME 🌸

raw_atomic_long_add_negative_acquire — atomic add and test if negative with acquire ordering 🦋

like, you add stuff. atomically. then you check if the result went negative. with acquire ordering. that's the whole vibe.

⭐ SYNOPSIS ⭐

bool raw_atomic_long_add_negative_acquire (long i , atomic_long_t *v );

🎀 ARGUMENTS 🎀

  • i — the long value you're adding 💖 that's it, that's the number
  • v — pointer to atomic_long_t 👑 the actual thing getting updated

✨ DESCRIPTION ✨

Atomically updates v to (v + i) with acquire ordering. no cap, it does both in one shot 🔥

Safe to use in noinstr code; prefer atomic_long_add_negative_acquire elsewhere. so like — if you're not in noinstr, why are you here? use the normal one. this one's the raw, lowkey-specialized variant. iykyk 💅

🌈 RETURN 🌈

true if the resulting value of v is negative, false otherwise 🫶

literally just a yes/no on "did we go negative". iconic behavior honestly.
