> Subject: [PATCH v2]PCI: hv: fix PCI-BUS domainID corruption
>
> Whenever PCI bus is added, HyperV guarantees the BUS id is unique. Even
> with
> that when a first device is added to the bus, it overrides bus domain ID
> with
> the device serial number. Sometime this can result in BUS ID not being
> unique.
> In this case, when PCI_BUS and a device added to the bus, even before the
> PCI
> BUS is added to kernel, the first device tends to overwrite the domain ID
> with
> 0. Since there exists a PCI bus with domain ID 0 already the PCI bus
> addition
> fails. This patch make sure when a device is added to a bus, it never
> updated
> the bus domain ID. Since we have the transparent SRIOV mode now, the
> short VF
> device name is no longer needed.
