📦 version 7.3.1, in nixpkgs unstable

💅 clean_an_unclean_leb(9) — like, the Kernel API Manual but make it cute 🎀

okay so bestie, welcome to clean_an_unclean_leb(9) from the Kernel API Manual ✨ this is the little recovery baddie that literally reads and writes a LEB to remove corruption. she's giving janitor energy but make it iconic 💖

🌸 NAME 🌸

clean_an_unclean_leb — read and write a LEB to remove corruption. that's it. that's the whole vibe. no cap 🫶

✨ SYNOPSIS ✨

int clean_an_unclean_leb (struct ubifs_info *c , struct
ubifs_unclean_leb *ucleb , void *sbuf );

she takes three things and returns an int, slay 👑

🦋 ARGUMENTS 🦋

  • c — the UBIFS file-system description object. the whole personality of the filesystem lives in here fr fr 💜
  • ucleb — unclean LEB information. yes bestie, the dirty little LEB info, it's all in here 🙈
  • sbuf — a LEB-sized buffer to use. LEB-sized. not "roughly the size", LEB-sized. respect the spec 💅

🔥 DESCRIPTION 🔥

so what does she actually do? okay so picture this: she reads a LEB up to a point that's pre-determined by the mount recovery (mount recovery is the main character here, she's just following the map 🗺️), checks the nodes, and then writes the result back to the flash. and that's how she cleans off any following corruption — or any non-fatal ECC errors. corruption? not on her watch. ECC errors that are non-fatal? also evicted 💀✨

it's giving "scrub the timeline" energy and honestly? obsessed.

lowkey important: this function returns 0 on success and a negative error code on failure. zero means she ate, negative means something went off and you should probably look at it 😭
