+	  This enables experimental support for the SMB2 (Server Message Block
+	  version 2) protocol. The SMB2 protocol is the successor to the
+	  popular CIFS and SMB network file sharing protocols. SMB2 is the
+	  native file sharing mechanism for recent versions of Windows
+	  operating systems (since Vista).  SMB2 enablement will eventually
+	  allow users better performance, security and features, than would be
+	  possible with cifs. Note that smb2 mount options also are simpler
+	  (compared to cifs) due to protocol improvements.
