In linux kernel since version 3.1 (release Date: 2011-10-24)
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.
