ubi_volume_notify(9)

💅 ubi_volume_notify(9) — like, the Kernel API Manual section 9, bestie

okay so picture this: it's kernel time, it's section 9, and the function is ubi_volume_notify. she's a little helper with main character energy and honestly? we're obsessed. let's get into it. ✨

---

🌸 SYNOPSIS 🌸

int ubi_volume_notify (struct ubi_device *ubi , struct ubi_volume *vol ,
int ntype );

that's the whole vibe right there. three args, one int coming back atcha. 🎀

---

🦋 ARGUMENTS 🦋

• ubi — the UBI device description object. like, the whole device, the big picture, the moment. 👑
• vol — the volume description object of the changed volume. specifically the volume that just went through something — that's our girl. 💖
• ntype — the notification type you wanna send (UBI_VOLUME_ADDED, etc). yes it says "etc" in the original, so no, i can't tell you the full list, don't come for me 😭

---

🌈 DESCRIPTION 🌈

so ubi_volume_notify is a helper function — lowkey the supportive bestie of the UBI world — and what she does is notify all subscribers about a volume change event. and when we say "change event", we mean all of it, no crumbs:

• creation
• removal
• re-sizing
• re-naming
• updating

like she literally covers every glow-up and every breakup. 💅

return value? she's giving zero in case of success, and a negative error code in case of failure. ngl, standard, but iconic. ✨

fr fr: if you get a negative number back, something did not slay. handle it. 🚨
