    igb: Check if subordinate VFs are assigned to virtual machines · 0224d663
    Greg Rose 提交于
    Kvm and the Xen pci-back driver will set a flag in the virtual function
    pci device dev_flags when the VF is assigned to a guest VM.  Before
    destroying subordinate VFs check to see if the flag is set and if so
    skip the call to pci_disable_sriov() to avoid system crashes.
    
    Copy the maintainer for the Xen pci-back driver.  Also CC'ing
    maintainers of all drivers found to call pci_disable_sriov().
