ubi_notify_all(9)

🌸 ubi_notify_all(9) — the Kernel API Manual page, bestie edition 🌸

Okay so this is ubi_notify_all(9) — yes, that's the name AND it's from the Kernel API Manual, we're doing both up front, no gatekeeping here. Sit down, hydrate, let's get into it 💖

---

✨ NAME ✨

ubi_notify_all — sends a notification to all volumes. That's it, that's the whole vibe. All of them. Every single one. 👑

---

✨ SYNOPSIS ✨

int ubi_notify_all (struct ubi_device *ubi , int ntype , struct
notifier_block *nb );

Look at her. Returns an int, takes three things. Iconic, honestly. 🎀

---

✨ ARGUMENTS ✨

Here's your cast of characters, no cap:

• ubi — the UBI device description object. Like, the whole device's little profile card 🪪
• ntype — the notification type you're sending (UBI_VOLUME_ADDED, etc). etc is doing so much heavy lifting there and I respect it 💅
• nb — the notifier to call. Yes, this one right here, this is the important one, keep your eye on it 👀

---

✨ DESCRIPTION ✨

So what actually happens? This function walks all volumes of the UBI device ubi and sends the ntype notification for each volume. Like a little tour. A little notification tour of every volume. Cute, honestly 🌈

Now here's the branching logic, and it matters, so listen up:

• If nb is NULL — then all registered notifiers are called 🫶
• Otherwise — only the nb notifier is called. Just the one. Exclusive. Main character energy ✨

And then — drumroll — it returns the number of sent notifications. A count. A little receipt of how many notifications went out 🔥
