attach_node_and_children(9)

💅 attach_node_and_children(9)

okay bestie, buckle up, because this is a page from the Kernel API Manual and honestly? The function name is lowkey lying to you. Let's get into it 🫶

---

✨ NAME ✨

attach_node_and_children — attaches nodes and its children to live tree.

🚨 CAUTION: misleading function name — if node @np already exists in the live tree, then children of @np are *not* attached to the live tree. This works for the current test devicetree nodes because such nodes do not have child nodes.

fr fr, read that caution twice. The name says "and children" but sometimes the children are just… not invited to the party 😭 It's fine though, because the current test devicetree nodes don't have child nodes anyway, so it all works out 💀

---

✨ SYNOPSIS ✨

void attach_node_and_children (struct device_node *np );

That's it. That's the whole signature. Iconic, honestly 👑

---

✨ ARGUMENTS ✨

• np — Node to attach to live tree

That's the one and only thing you're handing over: the node, bestie. She goes in, she gets attached to the live tree. Simple as that 🌸

---

✨ SEE ALSO ✨

• Kernel file ./drivers/of/unittest.c — update_node_properties(9), unittest_data_add(9)

Go read those if you want the full lore, iykyk 📖✨

🎀 sign-off 🎀

This page lives under ./drivers/of and it's dated October 2026 — so yeah, she's from the future and she's still out here attaching nodes. Slay 💅✨ Go forth and attach responsibly, bestie, and remember: read the caution, not just the name 🌈💖
