	  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.



	  Unless you are a developer or tester, say N.
