raw_atomic_l...xchg_relaxed(9)

💅 NAME 💅

okay so welcome to the Kernel API Manual, bestie — this page is raw_atomic_l...xchg_relaxed(9), and it's all about raw_atomic_long_xchg_relaxed, aka atomic exchange with relaxed ordering. no cap, that's the whole vibe ✨

✨ SYNOPSIS ✨

long raw_atomic_long_xchg_relaxed (atomic_long_t *v , long new );

🎀 ARGUMENTS 🎀

• v — pointer to atomic_long_t, so it's the address of the atomic long you're about to swap, bestie 💅
• new — a long value, and this is literally the value to assign 🫶

🦋 DESCRIPTION 🦋

okay so raw_atomic_long_xchg_relaxed atomically updates v to new with relaxed ordering. that's the whole plot, and it ate 🔥

it's safe to use in noinstr code; for everywhere else, prefer atomic_long_xchg_relaxed, periodt 💖

🌸 RETURN 🌸

it returns the original value of v — like, the value that was there before the swap. iconic receipt behavior, honestly 🧾✨
