ubifs_fast_find_empty(9)

💅 ubifs_fast_find_empty — the Kernel API Manual moment 🎀

okay so bestie, gather round, we're looking at ubifs_fast_find_empty(9) from the Kernel API Manual and honestly? it's a little baddie with one job. ✨

---

🌸 NAME 🌸

ubifs_fast_find_empty — bestie's whole personality is try to find an empty LEB quickly. that's it, that's the vibe. 💖

---

🦋 SYNOPSIS 🦋

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

like yes she's const, yes she returns a pointer to struct ubifs_lprops, and yes she takes exactly one arg. no cap. 🫶

---

🎀 ARGUMENTS 🎀

• c — the UBIFS file-system description object. that's the whole squad right there, she needs it, she's not doing anything without it. 💅

---

⭐ DESCRIPTION ⭐

okay so here's the tea: this function returns LEB properties for an empty LEB. or — plot twist 😭 — it returns NULL if the function is unable to find an empty LEB quickly. the keyword is quickly, she's not out here doing a whole exhaustive main-character search, she's doing a vibe check and dipping if it's not there. 🔥

lowkey important: NULL is a real possible answer here, not a bug. don't come for her. 💀
