ubifs_clean_lebs(9)

💅 ubifs_clean_lebs — yes bestie, we're in the Kernel API Manual (section 9, kernel internals, iykyk) 🎀

✨ NAME ✨

ubifs_clean_lebs — ok so this one cleans up LEBs that got recovered during a read-only mount. literally its whole job 💖

---

🦋 SYNOPSIS 🦋

int ubifs_clean_lebs (struct ubifs_info *c , void *sbuf );

🌸 ARGUMENTS 🌸

• c — the UBIFS file-system description object. the main character of the whole struct situation 👑
• sbuf — a buffer the size of a LEB that the function gets to use. think of it as the little scrub brush 🧚

---

💜 DESCRIPTION 💜

so here's the vibe: during recovery, UBIFS spots a LEB that needs to be written — but it wasn't written, because the fs was mounted read-only at the time. no cap, that's just how it went down. 🙈 This function goes and cleans that LEB up. When does this actually come up? When you're remounting into read-write mode. that's the moment, that's the slay ✨

This function returns 0 on success and a negative error code on failure. fr fr, that's the whole return contract, no surprises 💀
