ubi_enumerate_volumes(9)

💅 ubi_enumerate_volumes(9) 💅

ok so you found a page from the Kernel API Manual — specifically ubi_enumerate_volumes(9), bestie. UBI stands for Unsorted Block Images and this lil function is about to go tell everybody about every volume it can find. sit down, grab a 🍓, let's get into it.

---

✨ NAME ✨

ubi_enumerate_volumes — sends an "add" notification for all existing volumes. that's it, that's the whole job. she's a notifier girlie 🎀

---

🌸 SYNOPSIS 🌸

int ubi_enumerate_volumes (struct notifier_block *nb );

literally one parameter. one. we love a low-maintenance icon. 👑

---

🦋 ARGUMENTS 🦋

• nb — the notifier to call. this is the struct notifier_block * from the synopsis, so like… the person you're texting the news to. 📲

---

💖 DESCRIPTION 💖

okay so here's the vibe: this function walks all UBI devices and volumes and sends the UBI_VOLUME_ADDED notification for each volume. every single one. no skips, no "oops missed one," she's thorough like that. 💅

and the targeting logic? iconic:

• if nb is NULL, then all registered notifiers are called — full group chat blast 📢
• otherwise, only the nb notifier is called — a very private DM 💌

and she returns the number of sent notifications. so like, you get receipts. ✨
