ubifs_change_one_lp(9)

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

okay so picture this: it's a kernel manpage, it's giving "LEB properties need a glow-up", and it's literally called ubifs_change_one_lp. Yes bestie, one LEB. One. We're being specific. ✨

🌸 NAME 🌸

ubifs_change_one_lp — change LEB properties. that's it, that's the whole vibe check 💅

---

🦋 SYNOPSIS 🦋

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

look at all those params. she's got range. 👑

---

🎀 ARGUMENTS 🎀

• c — the UBIFS file-system description object. the main character of this whole operation fr.
• lnum — the LEB whose properties we're changing. yes, that LEB. 🫶
• free — amount of free space. how much room she's got.
• dirty — amount of dirty space. no cap, sometimes things get messy. 💀
• flags_set — flags to set. turn them ON. ⭐
• flags_clean — flags to clean. wipe them, fresh start. 🧚
• idx_gc_cnt — change to the count of idx_gc list. little counter adjustment, iykyk.

💖 DESCRIPTION 💖

So this function changes the properties of LEB lnum. That's the whole assignment. 🎯

It's a helper wrapper over same as in case of ubifs_change_lp — so like, ubifs_change_lp did it first and this one is the little sibling doing the exact same thing but for one LP. not me being a wrapper 💅

Returns zero in case of success and a negative error code in case of failure. so if you get 0, slay. if you get a negative number, that's your villain origin story, handle it. 😭

fr fr: check that return value. zero = iconic, negative = do not ignore.
