hv_pci_remove(9)

okay bestie, welcome to hv_pci_remove(9) from the Kernel API Manual 💖 we’re doing the remove-routine page for this VMBus channel, and it’s honestly a short one — so let’s not make it weird. no cap.

✨ NAME ✨

hv_pci_remove — Remove routine for this VMBus channel. That’s the whole name vibe, and yes it’s giving “cleanup era” 🧹✨.

void hv_pci_remove (struct hv_device *hdev );

It’s void, so there’s no return value to catch feelings over 💅.

💖 ARGUMENTS 💖

• hdev — VMBus's tracking struct for this root PCI bus. That’s the one argument, bestie — the VMBus tracking struct for this root PCI bus, periodt. 🫶
