change_category(9)

💅 change_category(9) — like, the LEB properties glow-up page

okay so this is a page from the Kernel API Manual, section 9, and it's all about change_category. yes bestie, we're in kernel-land today, put your hair up 🎀

---

✨ NAME ✨

change_category — the function that changes the category of LEB properties. that's it, that's the whole vibe 🦋

---

🌸 SYNOPSIS 🌸

void change_category (struct ubifs_info *c , struct ubifs_lprops *lprops );

it returns nothing (void, icon behaviour honestly) and it takes exactly two things. no more, no less 💅

---

🫶 ARGUMENTS 🫶

• c — the UBIFS file-system description object. like, the whole file system's little info card 🌈
• lprops — the LEB properties we're gonna re-categorize. yes, the LEB properties. they're getting a whole new aesthetic ✨

---

💖 DESCRIPTION 💖

so here's the tea ☕ — LEB properties get sorted into categories so that find operations can be fast. that's the whole point of the categorization, bestie, speed 🏎️

and the way that they change, okay, is that when the LEB properties themselves change, they must be re-categorized. not "should", not "maybe", must. no cap. 🔥

fr fr, if the properties change and you don't re-categorize, the fast-find situation is not gonna be slaying the way you want it to. keep them categories fresh 🧚
