ubifs_update_one_lp(9)

💅 ubifs_update_one_lp — like, the LEB properties glow-up edition

ok so this is ubifs_update_one_lp(9) from the Kernel API Manual, and honestly? it's giving "small function, big responsibilities." let's get into it 🫶

---

✨ NAME ✨

ubifs_update_one_lp — update LEB properties. that's it, that's the whole vibe. one LEB, one little properties refresh, no cap 💖

---

🌸 SYNOPSIS 🌸

int ubifs_update_one_lp (struct ubifs_info *c , int lnum , int free ,
       int dirty , int flags_set , int flags_clean );

like, six args, one int coming back at you. she's return-typed and ready 💅

---

🎀 ARGUMENTS 🎀

• c — the UBIFS file-system description object. your main character struct, fr fr 👑
• lnum — the LEB whose properties we're changing. that's the LEB. the one. 🦋
• free — amount of free space.
• dirty — amount of dirty space to add. note the word add, bestie, this is important, it comes back later 👀
• flags_set — flags to set.
• flags_clean — flags to clean.

---

⭐ DESCRIPTION ⭐

okay so here's the tea: this function is literally the same as ubifs_change_one_lp, with exactly one (1) iconic difference — dirty is added to the current dirty space, not substitutes it. she accumulates. she builds. she does not overwrite 😌✨

no additional lore, that's genuinely the whole thing, and honestly? slay for her. short and specific 💜

💀 real talk reminder: dirty here gets added to the current dirty space. if you were expecting it to replace the value, that is literally the other function. keep your dirty space math correct, i'm begging 🙈
