of_node_release(9)

💅 of_node_release(9) — Kernel API Manual 🎀

okay so bestie, welcome to the glow-up of a very specific kernel function 💖 this one lives in the Kernel API Manual, and honestly? it's a little backstage icon — nobody claps for it, but the whole show falls apart without it ✨

---

🌸 NAME 🌸

of_node_release — release a dynamically allocated node 🦋

like, the actual cleanup girlie of the device-tree world. she frees the node. that's the whole job. and she does it flawlessly, no cap 💅

---

✨ SYNOPSIS ✨

void of_node_release (struct kobject *kobj );

that's it. that's the whole signature. one void (she gives nothing back, she's not about that return-value life 🙈) and one pointer. slay.

---

🫶 ARGUMENTS 🫶

• kobj — the kernel object of the node that's about to be released 🎀 so basically, this is the node's kernel-object handle, and it's the one getting the goodbye treatment. main character energy fr fr 👑

---

💜 DESCRIPTION 💜

so here's the tea ☕ — inside of_node_put, this function gets passed to kref_put as the destructor. that's it. that's the entire vibe. she's the callback that shows up when the reference count finally hits zero and someone's gotta do the actual cleanup 😭

destructor duty — lowkey iconic of her honestly. kref_put calls her, she releases the dynamically allocated node, done. periodt 💅✨

💀 reminder bestie: this is release duty — she's the destructor, so she runs when the refcount says it's time. don't be out here treating her like a casual little helper function. she's the ending of an era. 🌈

and that's the whole page, bestie 🍓 this little gem came out of the kernel source tree at ./drivers/of, dated October 2026, and yes — the manual page itself is literally named of_node_release(9) 💖 go forth and reference-count responsibly, mwah 😘👑
