... If we test "rmmod pci-hyperv", I suspect the warning will be printed: hv_pci_remove() -> hv_pci_bus_exit() -> hv_pci_start_relations_work():In most case, it will not print anything.If I read the code correctly, I think the warning is printed _every time_ we unload pci-hyperv.
Okay I see what you mean. I'll remove this message.

It will print something if there is a PCI_BUS_RELATION work pending at the time of remove. The same goes to PCI_EJECT. In those cases, the message is valuable to troubleshooting.
