drm_mm_remove_node(9)

💅 drm_mm_remove_node(9) 💅

Okay bestie, welcome to the drm_mm_remove_node(9) page from the Kernel API Manual. This is the whole vibe: we're removing a memory node from the allocator. No cap, that's literally it.

---

✨ NAME ✨

drm_mm_remove_node — remove a memory node from the allocator. It's giving "cleanup era" and we're here for it.

---

🦋 SYNOPSIS 🦋

void drm_mm_remove_node (struct drm_mm_node *node );

---

💖 ARGUMENTS 💖

• node — the drm_mm_node you wanna remove. That's the whole argument, bestie. One node, one job.

---

🔥 DESCRIPTION 🔥

So like, this function just takes a node out of its drm_mm allocator. That's the tea. ☕

And here's the slay part: the node does not need to be cleared again before you can re-insert it into this allocator or any other drm_mm allocator. It's reusable, iconic, sustainable queen behavior. 💅✨

🚨 BUT BESTIE, LISTEN: it is a bug to call this function on an unallocated node. Like, absolutely do not. That's a red flag, a no-no, a "not me doing undefined behavior" moment. Do not pass go, do not collect $200. 🙈💀

🎀 SIGN-OFF 🎀

Peace out from the ./drivers/gpu/drm crew, dated October 2026. Stay allocated, stay iconic, and for the love of everything, don't call this on an unallocated node. Mwah! 💋🫶
