- Update config files: enable CONFIG_CIFS_SMB2
    
    cifs.ko is currently built with support for the base SMB1/CIFS dialect
    only. SMB1/CIFS support can be disabled in Windows 8.1 and Windows
    Server 2012 R2, and is completely unsupported with the Microsoft Azure
    File service, leaving cifs.ko users unable to access files on such
    servers without this change (fate#317480).
