configfs_register_group(9)

💅 configfs_register_group(9)

okay so bestie, welcome to the Kernel API Manual ✨ today we're talking about configfs_register_group and honestly? it's giving matchmaker energy 🫶 because it literally sets up a parent-child relationship between two groups. iconic behavior.

---

🌸 SYNOPSIS 🌸

int configfs_register_group (struct config_group *parent_group , struct config_group *group );

that's the whole vibe. one function, two structs, infinite possibilities 💖

---

🎀 ARGUMENTS 🎀

• parent_group — the parent group 🧚 the one doing the adopting, the main character of this whole arrangement
• group — the child group 🍓 the little one getting attached to its new parent, slay

---

✨ DESCRIPTION ✨

okay so here's what's happening: this function links the groups, creates a dentry for the child 👑 and then attaches that dentry to the parent's dentry. that's it. that's the whole thing. no cap.

think of it like adding a new folder inside another folder, except it's the kernel and everything is way more serious 💀 but the energy is the same honestly.

🔥 RETURN 🔥

• 0 on success — we ate, periodt 💅
• a negative errno code on error — not me crying in errno 😭
