set_ltab(9)

✨ set_ltab(9) ✨

okay so picture this: it's a <purple>Kernel API Manual</purple> page, section <cyan>9</cyan>, and the star of the show is set_ltab — yes bestie, the one that sets LPT LEB properties. tiny function, huge responsibility. let's get into it 💅

---

🌸 NAME 🌸

set_ltab — sets the LPT LEB properties. that's it, that's the whole vibe. short, iconic, to the point 🎀

---

🦋 SYNOPSIS 🦋

void set_ltab (struct ubifs_info *c , int lnum , int free , int dirty );

like look at that signature, she's literally so clean 😭 no surprises, no sneaky return value, just void and four args.

---

🔥 ARGUMENTS 🔥

• c — the UBIFS file-system description object. your whole filesystem's little personality profile, passed in by pointer 🫶
• lnum — the LEB number. which LEB we're talking about, no cap.
• free — amount of free space. keeping track of the emptiness, very philosophical of you ✨
• dirty — amount of dirty space. the mess. the chaos. the main character energy 💀

ngl, free and dirty are just numbers going into the LPT LEB properties — don't overthink them, this function is not the drama.
