🌸 kobject_init(9) — Kernel API Manual 🌸

okay so bestie, welcome to kobject_init, one of the most iconic little functions in the whole kernel API manual, no cap. it's your girl's guide to giving a kobject its whole personality before you yeet it out into the world. let's get into it 💅

✨ NAME ✨

kobject_init — Initialize a kobject structure. literally that's it, that's the whole job, and she does it beautifully 🎀

🦋 SYNOPSIS 🦋

void kobject_init (struct kobject *kobj , const struct kobj_type *ktype );

look at her. short. sweet. main character energy 👑

💖 ARGUMENTS 💖

  • kobj — pointer to the kobject to initialize. this is the lil guy you're about to set up, she's the whole moment fr
  • ktype — pointer to the ktype for this kobject. yes, her type. we love a kobject that knows what it is 🫶

🌈 DESCRIPTION 🌈

so the way this works is kobject_init properly initializes a kobject so that it can then be passed to the kobject_add call. like, before this she's just raw unstructured memory, and after this she's a whole functional member of society ✨

⚠️ and here's the part where you listen to me, bestie: after this function is called, the kobject MUST be cleaned up by a call to kobject_put, not by a call to kfree directly. that's not a suggestion, that's not a vibe check you can fail, that's a MUST. this is so that all of the memory is cleaned up properly. do not just kfree her, i'm begging you 😭💀

🔥 SEE ALSO 🔥

Kernel file ./lib/kobject.c — go read it, she's right there, iykyk 📖

and that's the page, bestie! 💜 this lil slice of manual heaven lives in ./lib and is dated October 2026 — and yes she's still signed kobject_init(9), iconic behavior, we stan a consistent queen 👑🎀💖
