ubi_get_volume_info(9)

💅 NAME

ubi_get_volume_info — bestie, this is the one that pulls the deets on a UBI volume for you ✨

It's giving "tell me everything about this volume" energy, and honestly? Iconic.

So quick vibe check: this is a Kernel API Manual situation (section 9, kernel-land, no cap 🧚), and what it does is get information about a UBI volume. That's it, that's the whole personality.

🌸 SYNOPSIS

void ubi_get_volume_info (struct ubi_volume_desc *desc , struct ubi_volume_info *vi );

Notice it returns void, bestie — it's not gonna hand you a status code, it just does the thing 🙈. The info lands in the struct you pass in.

---

🎀 ARGUMENTS

• desc — your volume descriptor. Like, this is the handle that says "yes, this exact volume, her, the one I want the tea on" 💅
• vi — the info gets stored here. You hand it the struct, it fills it in. That's the whole deal. 🫶

ngl, vi literally stands for "volume info" and if you remember that you're already winning. Lowkey the most sensible naming in the kernel.
