ubi_remove_volume(9)

📦 version 7.3.1, in nixpkgs unstable

💅 ubi_remove_volume(9) 💅

okay so this is a page from the Kernel API Manual, bestie — we're in the ubi section of the kernel, the whole UBI (unsorted block images) situation, and this particular function is the "bye bitch, this volume is GONE" one. no cap, it literally removes a volume. let's get into it ✨

🌸 NAME 🌸

ubi_remove_volume — remove volume. that's it. that's the whole vibe. deleting, but make it kernel-sanctioned 💅

🦋 SYNOPSIS 🦋

int ubi_remove_volume (struct ubi_volume_desc *desc , int no_vtbl );

it's giving function signature realness 🌈

🎀 ARGUMENTS 🎀

  • desc — the volume descriptor. like, the little handle that says "yes queen, this volume right here" 🫶
  • no_vtbl — if this is not zero, then do not change the volume table. that's the whole rule, lowkey simple 💖

✨ DESCRIPTION ✨

so <cyan>ubi_remove_volume</cyan> removes the volume that desc is describing. periodt. 💀

BUT — and this is the important part, bestie, do not skip this — the volume has to be opened in "exclusive" mode. like, exclusive. no sharing. main character energy only 👑. if you didn't open it exclusively, that's not it, and things are not gonna slay.

it returns zero in case of success, and a negative error code in case of failure. classic kernel behavior, fr fr 😭

and the caller has to have the ubi->device_mutex locked. that's not optional, that's not a suggestion, that's a requirement. lock it before you call this or you're gonna have a bad time 🙈

⚠️ recap of the rules so you don't fumble: "exclusive" mode open ✅, ubi->device_mutex locked ✅, check the return value ✅✅. do all three or don't call it at all 💅

🔥 SEE ALSO 🔥

the kernel file lives at ./drivers/mtd/ubi/vmt.c, and here are the besties it hangs out with:

it's giving "whole friend group of volume operations" and honestly? iconic. go read them, iykyk 🧚

okay that's the page, bestie 🎀 this one's sourced from ./drivers/mtd/ubi and dated October 2026 — so like, when you're citing it in your notes, that's the version vibe. mwah, go remove some volumes responsibly. slay 💖🌟
