💅 sysfs_group_change_owner — a kernel API manual moment

ok so bestie, welcome to sysfs_group_change_owner(9) — yes that's the whole title, section 9, Kernel API Manual vibes, and it is literally about one tiny job: changing who owns an attribute group. that's it. that's the whole slay. 🎀

✨ SYNOPSIS ✨

int sysfs_group_change_owner (struct kobject *kobj , const struct
       attribute_group *grp , kuid_t kuid , kgid_t kgid );

look at her. four arguments, returns an int, she's iconic and she knows it. 💅

🌸 ARGUMENTS 🌸

okay so let's meet the cast, no cap:

  • kobj — the kobject that contains the group. like, the whole container. the main character. the group's home address. 🏠
  • grp — the attribute group itself. the const struct attribute_group * in question. she's the one getting a new owner fr fr. 🦋
  • kuid — the new owner's kuid. yes, kuid, kernel-user-id flavored. 👑
  • kgid — the new owner's kgid. same energy, but group-y. kgid. 🍓

💖 DESCRIPTION 💖

so what does she actually do? she changes the owner of an attribute group. that's the vibe check and she passes it.

Returns 0 on success or error code on failure. that's the entire description bestie, don't @ me, the kernel devs kept it short and honestly? respect. 😭

like genuinely — 0 means slay, anything else is an error code and you should probably read it. error code = not the vibe. 🙈

🔥 SEE ALSO 🔥

okay this is the friend group, and they're all in Kernel file ./fs/sysfs/group.c so you know where to find them:

not me listing all twelve of them 💀 — but yes, all twelve, every single one, because we don't skip the boring parts in this house. group chat complete. ✨

and that's the page!! ./fs/sysfs is where she lives, she's stamped October 2026, and she's filed under sysfs_group_change_owner(9) — go forth and change some owners, bestie, you've got this 🫶🌸💜
