raw_atomic64..._inc_relaxed(9)

💅 raw_atomic64..._inc_relaxed(9) 💅

okay bestie, welcome to the Kernel API Manual page for raw_atomic64..._inc_relaxed(9) — yes, the raw 64-bit atomic fetch-inc-relaxed one. It's lowkey iconic and highkey exactly what it sounds like. 🎀

✨ NAME ✨

raw_atomic64_fetch_inc_relaxed — atomic increment with relaxed ordering

🌸 SYNOPSIS 🌸

s64 raw_atomic64_fetch_inc_relaxed (atomic64_t *v );

🎀 ARGUMENTS 🎀

• v — pointer to atomic64_t. That's the atomic64_t you're about to bump, periodt.

🦋 DESCRIPTION 🦋

Atomically updates v to (v + 1) with relaxed ordering.

Safe to use in noinstr code; prefer atomic64_fetch_inc_relaxed elsewhere. So if you're in noinstr land, slay; if not, take the other door, bestie. 🫶

✨ RETURN ✨

The original value of v. You get the before-the-+1 value back, no cap. 💖
