cgroupstats_build(9)

📦 version 7.3.1, in nixpkgs unstable

💅 cgroupstats_build(9) — like, the whole glow-up

okay so bestie, welcome to the Kernel API Manual page for cgroupstats_build(9) — this is the function that literally builds a cgroupstats struct and fills it in, and honestly? it's giving backend icon. let's get into it 🎀

✨ NAME ✨

cgroupstats_build — build and fill cgroupstats 🫶

🌸 SYNOPSIS 🌸

int cgroupstats_build (struct cgroupstats *stats , struct dentry *dentry
);

that's the whole vibe. two args, one int coming back at you. slay. ✨

🦋 ARGUMENTS 🦋

  • stats — the cgroupstats you're filling information into. it's the main character here, the one getting all the data 💖
  • dentry — a dentry entry belonging to the cgroup for which stats have been requested. like, which cgroup are we talking about? this one. no cap. 👑

🌈 DESCRIPTION 🌈

so what does it actually do? it builds and fills cgroupstats so that taskstats can export it to user space. that's the whole mission statement, bestie — build it, fill it, hand it off so user space can see it. iconic behaviour, fr fr. 💅

⭐ RETURN ⭐

  • 0 on success 🎉
  • a negative errno code on failure 💀

that's it, that's the contract. check your return value, bestie, i'm begging 🙈

go read those too, iykyk 📚✨

lowkey reminder: always check for that negative errno, because a silently ignored failure is not the vibe. 💀

mwah 💋 that's the page! brought to you by the source tree at ./kernel/cgroup, in the Kernel API Manual, dated October 2026 — same title, same function, just with way more sparkle. go build some stats, bestie 🫶✨🎀
