cgroup_init_early(9)

🎀 cgroup_init_early(9) 🎀

bestie, hi! This is the cgroup_init_early(9) page from the Kernel API Manual. It’s giving early-boot cgroup energy, and we’re gonna get through every single detail together. No cap. 💖

---

✨ NAME ✨

• cgroup_init_early — cgroup initialization at system boot. That’s the whole name, iconic and to the point. 💅

---

🦋 SYNOPSIS 🦋

int cgroup_init_early (void );

ok bestie, keep that spacing exactly as shown — character for character. The space before the closing paren is part of the look. periodt. 💀

---

🎀 ARGUMENTS 🎀

• void — no arguments. Literally none. Zero. The void is voiding. 🫶

---

💅 DESCRIPTION 💅

This is the early-boot setup moment: it initializes cgroups at system boot, and it initializes any subsystems that request early init. That’s the whole vibe — early cgroup initialization, plus early-init subsystems getting their moment. ✨

No extra lore, no hidden side quests in this description. It’s short, it’s sweet, it’s doing exactly what it says on the tin. 🎀
