cpuset_init_smp(9)

💅 cpuset_init_smp(9) — a Kernel API Manual moment

Okay bestie, welcome to the cpuset_init_smp(9) page — yes that's the whole manual name, it's giving "section 9, kernel API, no notes" ✨

---

🌸 NAME 🌸

cpuset_init_smp — initialize cpus_allowed

---

🎀 SYNOPSIS 🎀

void cpuset_init_smp (void );

---

🦋 ARGUMENTS 🦋

• void — no arguments. literally none. zero. the void is the whole personality here 💀

---

✨ DESCRIPTION ✨

Okay so here's the tea: this one finishes up the top cpuset after the cpu and node maps are initialized. That's it, that's the whole job — it's the little cleanup era at the end of setup, and honestly? iconic 🫶

Heads up: the synopsis takes no arguments and the description gives you no extras — so don't go looking for hidden flags, there are none, no cap 💅
