balloon_page_alloc(9)

🎈 balloon_page_alloc(9) 🎈

okay so bestie, this page is from the Kernel API Manual — manual name folded in, as requested — and it's all about balloon_page_alloc. It's giving very specific kernel-page energy, and we're gonna get into it. 💖

---

✨ NAME ✨

balloon_page_alloc — allocates a brand-new page for insertion into the balloon page list. Slay.

---

🫶 SYNOPSIS 🫶

struct page * balloon_page_alloc (void );

---

🎀 ARGUMENTS 🎀

• void — no arguments. Like, literally none, bestie. Zero. The vibe check is empty and that's the whole point. 💅

---

🌸 DESCRIPTION 🌸

Driver must call this function to properly allocate a new balloon page. That's the whole assignment. No cap.

Driver must call balloon_page_enqueue before definitively removing the page from the guest system.

🚨 bestie, that "must" is doing heavy lifting — it's not optional, and the order matters. Keep balloon_page_enqueue in the mix before you definitively remove that page from the guest system.

---

⭐ RETURN ⭐

You get back a struct page for the allocated page, or NULL on allocation failure. That's it. That's the return. 😭
