    iommu/vt-d: Defer domain removal if device is assigned to a driver · e7f9fa54
    Joerg Roedel 提交于
    When the BUS_NOTIFY_DEL_DEVICE event is received the device
    might still be attached to a driver. In this case the domain
    can't be released as the mappings might still be in use.
    
    Defer the domain removal in this case until we receivce the
    BUS_NOTIFY_UNBOUND_DRIVER event.
