	  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.

	  This enables support for the Server Message Block version 2

	  family of protocols, including SMB3.  SMB3 support is

	  enabled on mount by specifying "vers=3.0" in the mount

	  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.

	  In general SMB3 enables better performance, security

	  and features, than would be possible with CIFS (Note that

	  when mounting to Samba, due to the CIFS POSIX extensions,

	  CIFS mounts can provide slightly better POSIX compatibility

	  than SMB3 mounts do though). Note that SMB2/SMB3 mount

	  options are also slightly simpler (compared to CIFS) due

	  to protocol improvements.
