💖 vmballoon_pop(9) 💖

okay bestie, welcome to the Kernel API Manual — this is the page for vmballoon_pop(9), and it's literally the “just drop everything” move for the balloon. 🎈✨

🌸 NAME 🌸

vmballoon_pop — quickly release all pages allocate for the balloon. yes, that's the whole name-section tea. 🫖

✨ SYNOPSIS ✨

void vmballoon_pop (struct vmballoon *b );

🎀 ARGUMENTS 🎀

• b — pointer to the balloon. That's the whole guest list, bestie. 🎈

💅 DESCRIPTION 💅

So when the host decides to “reset” the balloon — for one reason or another — this function is the one that gets called. It's not a normal “deflate” situation: we do not (shall not) notify the host that the pages are being released. Periodt. The whole vibe is quick release, no host update. 💨
