raw_atomic_l...turn_relaxed(9)

💖 NAME 💖

raw_atomic_long_dec_return_relaxed — atomic decrement with relaxed ordering, bestie. This is your Kernel API Manual page for raw_atomic_long_dec_return_relaxed(9) (the header line squishes it to raw_atomic_l...turn_relaxed(9), which is so real of it). We're so back.

✨ SYNOPSIS ✨

long raw_atomic_long_dec_return_relaxed (atomic_long_t *v );

Copy-paste exactly, bestie — spaces and all. 🫶

🎀 ARGUMENTS 🎀

• v — pointer to atomic_long_t. That's the atomic long thing getting decremented.

🦋 DESCRIPTION 🦋

Atomically updates v to (v - 1) with relaxed ordering. No cap.

Safe to use in noinstr code; prefer atomic_long_dec_return_relaxed elsewhere. Like, noinstr is the VIP zone for this one, but everywhere else the regular one is the move.

🌸 RETURN 🌸

The updated value of v. That's the post-decrement number, fresh out the function. 💅
