balloon_page_enqueue(9)

🎈 NAME 🎈

okay so bestie, this is balloon_page_enqueue(9) from the Kernel API Manual, and it's literally the function that inserts a new page into the balloon page list. that's the whole name, no cap. 🫶

✨ SYNOPSIS ✨

void balloon_page_enqueue (struct balloon_dev_info *b_dev_info , struct
       page *page );

slay, that's the signature. 💅

🌸 ARGUMENTS 🌸

• b_dev_info — the balloon device descriptor where we will insert a new page. it's the designated spot, iykyk.
• page — the new page to enqueue - allocated using balloon_page_alloc. yes, that exact allocator, bestie.

🦋 DESCRIPTION 🦋

okay so drivers must call this function to properly enqueue a new allocated balloon page before definitively removing the page from the guest system. this is the required step, not a vibe suggestion. periodt. ✨

⚠️ real talk: drivers must not enqueue pages while page->lru is still in use, and must not use page->lru until a page was unqueued again. that's the boundary, bestie — respect it. 💀
