+	  This enables support for the Server Message Block version 2

+	  options. These protocols are the successors to the popular
+	  CIFS and SMB network file sharing protocols. SMB3 is the
+	  native file sharing mechanism for the more recent
+	  versions of Windows (Windows 8 and Windows 2012 and
+	  later) and Samba server and many others support SMB3 well.
