+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.
