ubifs_fast_find_frdi_idx(9)

💅 ubifs_fast_find_frdi_idx 💅

okay so bestie, welcome to the Kernel API Manual — yes we're in the kernel docs now, and yes this one is an actual function called ubifs_fast_find_frdi_idx. It's a lil' UBIFS helper and honestly it's giving "quick vibe check" energy. Let's get into it 🎀

---

✨ NAME ✨

ubifs_fast_find_frdi_idx — the function that tries to find a freeable index LEB, and does it quickly. Key word: tries. Lowkey it's a speedrun, not a guarantee 🏃‍♀️💨

---

🌸 SYNOPSIS 🌸

const struct ubifs_lprops * ubifs_fast_find_frdi_idx (struct ubifs_info
*c );

the way that return type is const struct ubifs_lprops *... iconic. note the lil' *c hanging out there on its own line, she's just built like that 💅

---

👑 ARGUMENTS 👑

• c — the UBIFS file-system description object. that's the whole thing, bestie, that's all she needs 🫶

---

🦋 DESCRIPTION 🦋

So what does she actually do? This function returns LEB properties for a freeable index LEB — or NULL if the function is unable to find a freeable index LEB quickly. fr fr that's it. no cap ✨

read that again though, because the NULL part is important: she's allowed to just shrug and hand you NULL when she can't find one quickly. it's not a bug, it's the whole design. ngl that's kind of main character energy — she doesn't overcommit 😌
