💅 xdp_unreg_page_pool(9) — Kernel API Manual 🎀

okay bestie, this one's from the Kernel API Manual and it's honestly a little icon: xdp_unreg_page_pool. Let's get into it ✨

---

🌸 NAME 🌸

xdp_unreg_page_pool — unregisters &page_pool from the memory providers list 🫶

---

🦋 SYNOPSIS 🦋

void xdp_unreg_page_pool (const struct page_pool *pool );

---

💖 ARGUMENTS 💖

• pool — the page_pool you wanna unregister, no cap 🌈

---

✨ DESCRIPTION ✨

So this is basically the shorthand for manually unregistering page pools — it's giving "convenience function, main character energy" 💅

🚨 BUT listen: if the pool was previously attached to an RxQ info, it must be detached first. Like, do the detach first or it's gonna be a whole thing 😭
