ubi_eba_get_ldesc(9)

📦 version 7.3.1, in nixpkgs unstable

💅 ubi_eba_get_ldesc(9) — like, the whole vibe of a LEB, bestie

okay so this is a page straight out of the Kernel API Manual — the function is ubi_eba_get_ldesc(9) and honestly? she's a little baby function but she's doing her best and we support her 🫶

✨ NAME ✨

ubi_eba_get_ldesc — get information about a LEB 💖

(LEB = logical eraseblock, iykyk. she's the logical one, the main character of the eraseblock world 👑)

🌸 SYNOPSIS 🌸

void ubi_eba_get_ldesc (struct ubi_volume *vol , int lnum , struct
       ubi_eba_leb_desc *ldesc );

no cap, that's the whole signature. void return, three args, she takes them and she fills them in. periodt ✨

🎀 ARGUMENTS 🎀

  • vol — the volume description object. literally which volume we're snooping on, bestie 🌸
  • lnum — the logical eraseblock number. like the index, the address in logical-land, the where 💅
  • ldesc — the LEB descriptor to fill. she hands you this empty little container and you fill it with knowledge 🎁
ngl, ldesc is an out-param vibes situation — you give it to the function, the function stuffs info into it. fill it up, queen 💖

🦋 DESCRIPTION 🦋

okay so the whole point: this is how you query information about a specific LEB 🕵️‍♀️✨

right now? she's lowkey only returning the physical position of the LEB. that's it. that's the tea ☕ but here's the thing — she will be extended to provide more information. the way that she's future-proofed 😭 she's growing, she's evolving, she's in her expansion era 🌈

so like, don't get too attached to the current output set — it's giving "starter pack" energy. today it's just the physical position, tomorrow? who knows 💀

🔥 SEE ALSO 🔥

bestie the SEE ALSO section is stacked. it's giving entire ecosystem. buckle up, we're listing all of them because everyone deserves their moment 💅✨

ok so real talk: this is kernel API territory 🫣 misusing it is not a cute look. read the source, respect the locks, and remember she's still growing into her full feature set. no cap 💀

and that's the page!! ✨🦋 source vibes live in ./drivers/mtd/ubi, this whole thing is dated October 2026, and it's from your fave Kernel API Manual — go forth and query those LEBs, bestie, you're gonna slay 🎀💖🌟
