💅 hv_eject_device_work(9) — from the Kernel API Manual, bestie 🎀

okay so picture this: it's a kernel API manual page, it's iconic, it's giving "hyperv PCI hotplug but make it dramatic" — and we're gonna read it together. no cap. 🦋

✨ NAME ✨

hv_eject_device_work — the function that handles ejection, but like… asynchronously 💫 (yes, the whole vibe is "bye bestie, we'll do it in the background")

🌸 SYNOPSIS 🌸

void hv_eject_device_work (struct work_struct *work );

that's it. that's the whole signature. short, sweet, ate. 👑

🫶 ARGUMENTS 🫶

  • work — a Work struct that's embedded right inside the internal device struct 🧚 it's literally just chilling in there, waiting for its moment

💖 DESCRIPTION 💖

so this function? it handles ejecting a device. main character energy. 🔥

Here's the tea though — Windows will attempt to gracefully eject a device, and it waits 60 seconds to hear back from the guest OS that this actually completed successfully. sixty whole seconds. that's a long time to be left on read ngl 😭

And if this timer expires, the device will be forcibly removed. no warning, no "we need to talk", just gone. it's giving blocked. 💀 so like, polite first, then unceremonious yank.

⚠️ note bestie: the graceful path is the 60-second wait, and the fallback is straight-up forced removal. that's just how it is, not me being dramatic — okay maybe a little dramatic, but it's accurate. ✨
