+config CIFS
+        tristate "CIFS support (advanced network filesystem, SMBFS successor)"
+        depends on INET
+        select NLS
+        help
+          This is the client VFS module for the Common Internet File System
+          (CIFS) protocol which is the successor to the Server Message Block
+          (SMB) protocol, the native file sharing mechanism for most early
+          PC operating systems.  The CIFS protocol is fully supported by
+          file servers such as Windows 2000 (including Windows 2003, NT 4
+          and Windows XP) as well by Samba (which provides excellent CIFS
+          server support for Linux and many other operating systems). Limited
+          support for OS/2 and Windows ME and similar servers is provided as
+          well.
+
+          The cifs module provides an advanced network file system
+          client for mounting to CIFS compliant servers.  It includes
+          support for DFS (hierarchical name space), secure per-user
+          session establishment via Kerberos or NTLM or NTLMv2,
+          safe distributed caching (oplock), optional packet
+          signing, Unicode and other internationalization improvements.
+          If you need to mount to Samba or Windows from this machine, say Y.
+
+config CIFS_STATS
+        bool "CIFS statistics"
+        depends on CIFS
+        help
+          Enabling this option will cause statistics for each server share
+          mounted by the cifs client to be displayed in /proc/fs/cifs/Stats
+
+config CIFS_STATS2
+        bool "Extended statistics"
+        depends on CIFS_STATS
+        help
+          Enabling this option will allow more detailed statistics on SMB
+          request timing to be displayed in /proc/fs/cifs/DebugData and also
+          allow optional logging of slow responses to dmesg (depending on the
+          value of /proc/fs/cifs/cifsFYI, see fs/cifs/README for more details).
+          These additional statistics may have a minor effect on performance
+          and memory utilization.
+
+          Unless you are a developer or are doing network performance analysis
+          or tuning, say N.
+
+config CIFS_WEAK_PW_HASH
+        bool "Support legacy servers which use weaker LANMAN security"
+        depends on CIFS
+        help
+          Modern CIFS servers including Samba and most Windows versions
+          (since 1997) support stronger NTLM (and even NTLMv2 and Kerberos)
+          security mechanisms. These hash the password more securely
+          than the mechanisms used in the older LANMAN version of the
+          SMB protocol but LANMAN based authentication is needed to
+          establish sessions with some old SMB servers.
+
+          Enabling this option allows the cifs module to mount to older
+          LANMAN based servers such as OS/2 and Windows 95, but such
+          mounts may be less secure than mounts using NTLM or more recent
+          security mechanisms if you are on a public network.  Unless you
+          have a need to access old SMB servers (and are on a private
+          network) you probably want to say N.  Even if this support
+          is enabled in the kernel build, LANMAN authentication will not be
+          used automatically. At runtime LANMAN mounts are disabled but
+          can be set to required (or optional) either in
+          /proc/fs/cifs (see fs/cifs/README for more detail) or via an
+          option on the mount command. This support is disabled by
+          default in order to reduce the possibility of a downgrade
+          attack.
+
+          If unsure, say N.
+
+config CIFS_UPCALL
+          bool "Kerberos/SPNEGO advanced session setup"
+          depends on CIFS && KEYS
+          help
+            Enables an upcall mechanism for CIFS which accesses
+            userspace helper utilities to provide SPNEGO packaged (RFC 4178)
+            Kerberos tickets which are needed to mount to certain secure servers
+            (for which more secure Kerberos authentication is required). If
+            unsure, say N.
+
+config CIFS_XATTR
+        bool "CIFS extended attributes"
+        depends on CIFS
+        help
+          Extended attributes are name:value pairs associated with inodes by
+          the kernel or by users (see the attr(5) manual page, or visit
+          <http://acl.bestbits.at/> for details).  CIFS maps the name of
+          extended attributes beginning with the user namespace prefix
+          to SMB/CIFS EAs. EAs are stored on Windows servers without the
+          user namespace prefix, but their names are seen by Linux cifs clients
+          prefaced by the user namespace prefix. The system namespace
+          (used by some filesystems to store ACLs) is not supported at
+          this time.
+
+          If unsure, say N.
+
+config CIFS_POSIX
+        bool "CIFS POSIX Extensions"
+        depends on CIFS_XATTR
+        help
+          Enabling this option will cause the cifs client to attempt to
+          negotiate a newer dialect with servers, such as Samba 3.0.5
+          or later, that optionally can handle more POSIX like (rather
+          than Windows like) file behavior.  It also enables
+          support for POSIX ACLs (getfacl and setfacl) to servers
+          (such as Samba 3.10 and later) which can negotiate
+          CIFS POSIX ACL support.  If unsure, say N.
+
+config CIFS_DEBUG2
+        bool "Enable additional CIFS debugging routines"
+        depends on CIFS
+        help
+           Enabling this option adds a few more debugging routines
+           to the cifs code which slightly increases the size of
+           the cifs module and can cause additional logging of debug
+           messages in some error paths, slowing performance. This
+           option can be turned off unless you are debugging
+           cifs problems.  If unsure, say N.
+
+config CIFS_EXPERIMENTAL
+          bool "CIFS Experimental Features (EXPERIMENTAL)"
+          depends on CIFS && EXPERIMENTAL
+          help
+            Enables cifs features under testing. These features are
+            experimental and currently include DFS support and directory
+            change notification ie fcntl(F_DNOTIFY), as well as the upcall
+            mechanism which will be used for Kerberos session negotiation
+            and uid remapping.  Some of these features also may depend on
+            setting a value of 1 to the pseudo-file /proc/fs/cifs/Experimental
+            (which is disabled by default). See the file fs/cifs/README
+            for more details.  If unsure, say N.
+
+config CIFS_DFS_UPCALL
+          bool "DFS feature support (EXPERIMENTAL)"
+          depends on CIFS_EXPERIMENTAL
+          depends on KEYS
+          help
+            Enables an upcall mechanism for CIFS which contacts userspace
+            helper utilities to provide server name resolution (host names to
+            IP addresses) which is needed for implicit mounts of DFS junction
+            points. If unsure, say N.
