balloon_page_insert(9)

💖 balloon_page_insert(9) 💖

okay so bestie, welcome to the Kernel API Manual — this is balloon_page_insert, and honestly? she's a little diva with one very important rule. let's get into it 🎀

---

✨ NAME ✨

balloon_page_insert — insert a page into the balloon's page list and make the page->private assignment accordingly. that's it, that's the whole vibe. she inserts, she assigns, she leaves. 💅

---

🌸 SYNOPSIS 🌸

void balloon_page_insert (struct balloon_dev_info *balloon , struct page *page );

returns void, so don't go looking for a return value, there isn't one, periodt. ✨

---

🦋 ARGUMENTS 🦋

• balloon — pointer to the balloon device. yes, an actual pointer to a struct balloon_dev_info. she needs to know which balloon, bestie 🎈
• page — the page to be assigned as a 'balloon page'. this is the one getting the whole main character treatment 👑

---

🔥 DESCRIPTION 🔥

so here's the tea: the caller must ensure the balloon_pages_lock is held. not optionally. not "if you feel like it." must. that lock is the entire vibe check for this function and you do not want to fail it 😭

no cap — if you're calling this without holding balloon_pages_lock, you're doing it wrong and the kernel is not gonna be nice about it 💀

that's genuinely the whole description. she's short, she's efficient, she's iconic. 🌟
