🌸 atomic64_ad...tive_relaxed(9) — Kernel API Manual 🌸

💖 NAME 💖

atomic64_add_negative_relaxed — atomic add and test if negative with relaxed ordering. That's the whole assignment, bestie: add, then vibe-check the sign, with relaxed ordering. ✨

✨ SYNOPSIS ✨

bool atomic64_add_negative_relaxed (s64 i , atomic64_t *v );

🎀 ARGUMENTS 🎀

  • i — s64 value to add. The number you're bringing to the function.
  • v — pointer to atomic64_t. The atomic64_t that's getting updated, main character energy.

🦋 DESCRIPTION 🦋

Okay so literally, this atomically updates v to (v + i) with relaxed ordering. No cap, that's the move. 🫶

⚠️ Unsafe to use in noinstr code — use raw_atomic64_add_negative_relaxed there instead. Do not ignore this, bestie; it's giving "wrong context" energy and the kernel will not be slay about it. 💀

⭐ RETURN ⭐

true if the resulting value of v is negative, false otherwise. That's it. That's the tea. 💅
