free_cpuset(9)

💖 NAME 💖

free_cpuset — bestie, the whole job is right there in the name: it frees the cpuset. That's it, that's the vibe. Short, sweet, main character energy, no notes ✨

🎀 SYNOPSIS 🎀

void free_cpuset (struct cpuset *cs );

Literally one line, and yes, the spacing is exactly like that — we do not mess with the code, periodt 💅

🦋 ARGUMENTS 🦋

• cs — the cpuset that's getting freed. That's the one. Hand it over and let it go 🫶

That's the whole page, bestie — this lil kernel API manual entry (section 9, the Kernel API Manual, if you're keeping track 📓) comes to you from the ./kernel/cgroup source, dated October 2026. Slay, bye! 🎀✨
