STRUCT OF_CHANGESET(9)

🎀 struct of_changeset(9) 🎀

Okay bestie, welcome to the struct of_changeset(9) page from the Kernel API Manual — yes we're literally in the kernel docs rn, and this one is short but it's giving "small but mighty" energy, no cap 💅

---

✨ NAME ✨

struct of_changeset — it's the changeset tracker structure, that's it, that's the whole vibe 🦋

---

✨ SYNOPSIS ✨

Here's the actual shape of the thing, copy it exactly pls because kernel structs do not play around:

struct of_changeset {
    struct list_head entries;
 };

---

✨ Members ✨

• entries — a list_head for the changeset entries 🌸 like, it's literally the little list-link that holds all your entries together. That's the whole member list, one (1) icon, we stan a minimalist king 👑

---

✨ Description ✨

So here's the tea ☕ — changesets are a super convenient way to apply bulk changes to the live tree. Think of it as your group-chat "apply to all" button, except it's for device tree nodes 🧚

But here's the important part, and I need you to listen: if something errors out, the changes get rolled back. All of them. It's giving undo-button but make it automatic 😭✨

And that's not even the best bit — changesets live on after the initial application. So if you don't destroy them after you're done using them, you can revert the whole thing later in one single call. One. Call. Highkey iconic 👑

Lowkey a gentle heads-up: if you don't destroy the changeset after use, you're keeping it around — and that's exactly why the single-call revert is still available to you. Plan accordingly, bestie 🫶
