💅 ubifs_fast_find_freeable(9) 💅

okay bestie, so this page is from the Kernel API Manual and it's literally called ubifs_fast_find_freeable(9) — say that five times fast, iykyk. it's a tiny little kernel function page and we're gonna get through it together, no cap. 🫶

---

✨ NAME ✨

ubifs_fast_find_freeable — try to find a freeable LEB quickly.

that's it. that's the whole vibe. quick search, freeable LEB, moving on. 🎀

---

✨ SYNOPSIS ✨

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

yes the line break is right there in the middle, don't come for me, that's just how the page is laid out. 😭

---

✨ ARGUMENTS ✨

• c — the UBIFS file-system description object. your whole file-system situation, packaged up in one lil struct. she's the main character here. 👑

---

✨ DESCRIPTION ✨

so what does it do?? it returns the LEB properties for a freeable LEB. and if it can't find a freeable LEB quickly? it just hands you back NULL. no drama, no waiting, no searching the whole entire file system — the whole point is speed, bestie. ⚡

literally: freeable LEB found → you get the lprops. not found fast enough → NULL. that's the entire plot. 🌸
