📦 version 7.3.1, in nixpkgs unstable

💅 raw_atomic_inc_return_acquire(9) 💅

okay bestie, welcome to the Kernel API Manual ✨ — this one's a single function out of the giant raw_atomic family tree, so let's get into it 🫶

🌸 NAME 🌸

raw_atomic_inc_return_acquire — atomic increment with acquire ordering. that's it, that's the whole personality 💖

✨ SYNOPSIS ✨

int raw_atomic_inc_return_acquire (atomic_t *v );

literally just hand it a pointer and it does the thing 🔥

🎀 ARGUMENTS 🎀

  • v — pointer to atomic_t. yes queen, the actual atomic variable you want to bump 👑

🦋 DESCRIPTION 🦋

So like — atomically updates v to (v + 1) with acquire ordering. one clean little increment, no torn reads, no drama 💅

ngl the important bit: it's safe to use in noinstr code 😭 which is like the fancy exclusive club of kernel contexts. but everywhere else? prefer atomic_inc_return_acquire instead. fr fr, that's the takeaway 🫶

⭐ RETURN ⭐

The updated value of v. so like, the new number after the increment, not the old one 💖

okay that's the whole page, bestie!! you ate that 🍓 this little icon lives in ./include/linux/atomic, and this edition dropped October 2026 — so like, go forth and increment atomically with acquire ordering, mwah 💜🧚
