πŸ“¦ version 7.3.1, in nixpkgs unstable

✨ ubifs_recover_log_leb(9) β€” the recovery glow-up πŸ’…

okay so bestie, welcome to the kernel API manual page for ubifs_recover_log_leb, straight out of ./fs/ubifs πŸ¦‹ this one's a UBIFS internal, so it's giving "deep kernel lore" but honestly? it's lowkey iconic once you get the vibe.


🌸 NAME 🌸

ubifs_recover_log_leb β€” literally scans and recovers a log LEB. that's the whole assignment, no cap πŸ’–


πŸŽ€ SYNOPSIS πŸŽ€

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 🫢


✨ ARGUMENTS ✨

  • c β€” the UBIFS file-system description object, aka the main character of this whole operation πŸ‘‘
  • lnum β€” LEB number. that's the one, girl 🎯
  • offs β€” offset. yes, an offset. we stan precision πŸ’…
  • sbuf β€” a LEB-sized buffer to use. LEB-sized, not negotiable, don't be out here with the wrong size πŸ™ˆ

πŸ’œ DESCRIPTION πŸ’œ

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 πŸ”₯

and then the returns β€” this function returns 0 on success and a negative error code on failure. cute, simple, classic kernel behaviour 😭

ngl a negative error code is never the vibe, but at least it's honest about it πŸ’€

and that's the page, bestie β€” mwah πŸ’‹

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 πŸ’€). hope recovery treats you gently, and remember: only the last log LEB, okay? iykyk πŸ“πŸ’…
