πŸ’– kset_create(9) πŸ’–

okay so bestie, welcome to the kset_create page from the Kernel API Manual β€” yes the whole manual, we're doing this, grab a lil snack πŸ“


✨ NAME ✨

kset_create β€” literally Create a struct kset dynamically. that's it, that's the whole vibe πŸŽ€


πŸ¦‹ SYNOPSIS πŸ¦‹

struct kset * kset_create (const char *name , const struct
kset_uevent_ops *uevent_ops , struct kobject *parent_kobj );

like yes it's three args, don't panic, we'll get through it together πŸ’…


🌸 ARGUMENTS 🌸

  • name β€” the name for the kset. that's it. that's the name. it's giving "name" energy πŸ‘‘
  • uevent_ops β€” a struct kset_uevent_ops for the kset. you hand it the ops, it does the uevent thing, iykyk πŸ”₯
  • parent_kobj β€” the parent kobject of this kset, if any. note the "if any" β€” so it can be nobody's child, main character energy fr fr ⭐

πŸ’œ DESCRIPTION πŸ’œ

okay so here's the tea β˜• β€” this function creates a kset structure dynamically. not statically, not on some sad little stack, dynamically, slay.

This structure can then be registered with the system and show up in sysfs with a call to kset_register. yup, that's the whole glow-up: you create it, you register it, it appears in sysfs like ✨manifesting✨

When you are finished with this structure, if kset_register has been called, call kset_unregister and the structure will be dynamically freed when it is no longer being used. so like, clean up after yourself bestie, and the freeing happens whenever it's actually done being used β€” not a moment before, no cap 🫢

⚠️ important lil note: the "call kset_unregister" instruction is conditional β€” if kset_register has been called. don't come for me, that's literally what the page says πŸ’€

If the kset was not able to be created, NULL will be returned. so always check your return value, like always, every time, periodt πŸ™ˆ

like the entire kobject/kset friend group showed up to the party and honestly? obsessed πŸ§šπŸ’–


and that's the page!! mwah πŸ’‹ it lives in ./lib, dated October 2026 β€” so go forth, create your ksets dynamically, check for NULL, and unregister responsibly. bye bestie πŸ¦‹πŸ’œ
