vmballoon_work(9)

📦 version 7.3.1, in nixpkgs unstable

💖 vmballoon_work(9) — like, the kernel API manual bestie 💖

okay so real talk, this is vmballoon_work(9) from the Kernel API Manual, and it's genuinely one of the cutest little workqueue functions in the whole ./drivers/misc folder. sit down, grab a strawberry drink 🍓, and let's get into it.

✨ NAME ✨

vmballoon_work — the periodic balloon worker that handles reset, inflation and deflation. yes bestie, all three. she does it all 💅

🎀 SYNOPSIS 🎀

void vmballoon_work (struct work_struct *work );

that's it. that's the whole signature. and it returns void, so like… no feedback, no drama, she just does it. main character energy fr fr 👑

🦋 ARGUMENTS 🦋

  • work — pointer to the work_struct which is provided by the workqueue. that's the whole argument, one (1) single pointer, and the workqueue is the one handing it over. she's not picky, she's grateful 🙏

🌸 DESCRIPTION 🌸

okay so what actually happens: she resets the protocol if needed, gets the new size, and adjusts the balloon as needed. then she does it all again in 1 sec. and again. and again. forever. that's the gig. iconic repetitive queen behavior 💀✨

like literally — reset if needed → grab the new size → adjust the balloon → wait 1 sec → repeat. that's the loop, no cap. 🫶

💜 SEE ALSO 💜

the kernel file ./drivers/misc/vmw_balloon.c and honestly her entire friend group:
