β¨ ubifs_recover_log_leb(9) β the recovery glow-up π
okay so bestie, welcome to the kernel API manual page for ubifs_recover_log_leb, straight out of ./fs/ubifs π¦ this one's a UBIFS internal, so it's giving "deep kernel lore" but honestly? it's lowkey iconic once you get the vibe.
πΈ NAME πΈ
ubifs_recover_log_leb β literally scans and recovers a log LEB. that's the whole assignment, no cap π
π SYNOPSIS π
struct ubifs_scan_leb * ubifs_recover_log_leb (struct ubifs_info *c ,
int lnum , int offs , void *sbuf );
look at that signature, we love a struct pointer return type π«Ά
β¨ ARGUMENTS β¨
cβ the UBIFS file-system description object, aka the main character of this whole operation πlnumβ LEB number. that's the one, girl π―offsβ offset. yes, an offset. we stan precision πsbufβ a LEB-sized buffer to use. LEB-sized, not negotiable, don't be out here with the wrong size π
π DESCRIPTION π
so what this function actually does is scan a LEB, but with extra care β it's built to cater for errors that might have been caused by unclean reboots that we're attempting to recover from. and here's the key detail, bestie, do not miss it: assume that only the last log LEB can be corrupted by an unclean reboot. just the last one. that's the assumption, that's the lore π₯
and then the returns β this function returns 0 on success and a negative error code on failure. cute, simple, classic kernel behaviour π
ngl a negative error code is never the vibe, but at least it's honest about it π

and that's the page, bestie β mwah π
so this manual page came from ./fs/ubifs, dated October 2026, source/version field being ./fs/ubifs itself (yes, that's what it says, don't come for me π). hope recovery treats you gently, and remember: only the last log LEB, okay? iykyk ππ
