vmballoon_init_batching(9)

💫 vmballoon_init_batching(9) 💫

okay so bestie, welcome to the Kernel API Manual — this little cutie lives in section 9 and her whole personality is "turn on batching mode". ✨

---

🎀 NAME 🎀

vmballoon_init_batching — enable batching mode. that's it, that's the vibe 💅

---

🌸 SYNOPSIS 🌸

int vmballoon_init_batching (struct vmballoon *b );

---

🦋 ARGUMENTS 🦋

• b — pointer to struct vmballoon. like, the balloon struct itself. she needs to know which balloon you're talking about, obviously 🎈

---

👑 DESCRIPTION 👑

so here's the tea ☕ — this function enables batching in two iconic little moves:

1. it allocates a page for communication with the hypervisor 🫶
2. it enables the static_key so that batching actually gets used ⭐

that's the whole plot. no cap, she's a two-step main character and she ate. 🔥

---

💖 RETURN 💖

zero on success 💚 — or an appropriate error-code if things went sideways 😭 (as error codes do).
