dump_lpt_leb(9)

💅 dump_lpt_leb(9) — from the Kernel API Manual, bestie ✨

okay so picture this: you're deep in the kernel, you're in dump_lpt_leb(9) territory, and you just need someone to dump an LPT LEB for you. that's the whole vibe. that's the name. 🎀

---

🌸 SYNOPSIS 🌸

void dump_lpt_leb (const struct ubifs_info *c , int lnum );

no return value, no drama, it just does the thing. periodt. 💅

---

✨ ARGUMENTS ✨

• c — the UBIFS file-system description object 🦋 (yes, the whole file-system is described in one little struct, she's an icon)
• lnum — the LEB number you wanna dump 👑 like, which one, bestie, point at it

---

💖 DESCRIPTION 💖

so this function right here dumps an LEB from the LPT area. and before you're like "why is this its own function, that's giving redundant," listen — nodes in this area are very different from nodes in the main area. like, not even close. they do not have common headers, they do not have 8-byte alignments, etc. 😭 completely different species. so we have a whole separate function just for dumping LPT area LEBs, and honestly? she deserves it.

🚨 real talk though: the LPT has to be locked by the caller. like, that's on you, not on this function. lock it first or things get weird. no cap.
