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