ubifs_add_to_cat(9)

💖 ubifs_add_to_cat(9) 💖

okay so welcome to the Kernel API Manual bestie, today we're looking at ubifs_add_to_cat(9) and honestly? it's giving "small function, big job." let's get into it 🫶

---

✨ NAME ✨

ubifs_add_to_cat — adds LEB properties to a category list or heap. that's it. that's the whole vibe. 💅

---

🌸 SYNOPSIS 🌸

void ubifs_add_to_cat (struct ubifs_info *c , struct ubifs_lprops
*lprops , int cat );

yes it returns void, so no exit-status drama here, she just does the thing ✨

---

🎀 ARGUMENTS 🎀

• c — the UBIFS file-system description object. like, the whole filesystem's main character data. 👑
• lprops — the LEB properties you're adding. this is the actual payload, the guest of honor. 🦋
• cat — the LEB category you're adding it to. which list/heap is getting blessed today. 🌸

---

💜 DESCRIPTION 💜

LEB properties are categorized to enable fast find operations. that's the entire reason this exists, no cap — categorizing means later lookups can ✨zoom✨ instead of scrolling through everything like a loser. 🔥
