process_lvol(9)

📦 version 7.3.1, in nixpkgs unstable

💅 NAME 💅

process_lvol — bestie, this is the one that processes the layout volume. Periodt.

So like, this page lives in the Kernel API Manual (yes, that's the manual name, we're fancy now ✨), and it's all about one little function that handles the layout volume for UBI. Let's get into it 🫶

✨ SYNOPSIS ✨

struct ubi_vtbl_record * process_lvol (struct ubi_device *ubi , struct
ubi_attach_info *ai , struct ubi_ainf_volume *av );

That's the whole signature, no cap. It hands you back a struct ubi_vtbl_record *, and it wants three pointers: ubi, ai, and av. Obsessed with a clean three-arg function ngl 💖

🎀 ARGUMENTS 🎀

  • ubi — the UBI device description object. It's literally the device's whole personality, okay? It's where the device info lives 💅
  • ai — the attaching information. Like, the whole "we're attaching rn" lore 🦋
  • av — the layout volume attaching information. Same vibe as ai but specifically for the layout volume, iykyk 🌸

🔥 DESCRIPTION 🔥

Okay so here's the main character energy: this function is responsible for reading the layout volume, making sure it is not corrupted (vibe check on the volume 🧚), and recovering from corruptions if needed. So if the layout volume shows up looking a mess, process_lvol is the one fixing it, fr fr.

Returns the volume table in case of success, and a negative error code in case of failure. So if you get a negative number back, that's your sign 😭 — it did not slay.

Bestie, remember: success = volume table. Failure = negative error code. Don't get it twisted 💜
