-          This is the journalling version of the Second extended file system

-          (method to organize files on a storage device) for hard disks.
-          The journalling code included in this driver means you do not have
-          to run e2fsck (file system checker) on your file systems after a
-          crash.  The journal keeps track of any changes that were being made
-          at the time the system crashed, and can ensure that your file system
-          is consistent without the need for a lengthy check.
-          Other than adding the journal to the file system, the on-disk format
-          of ext3 is identical to ext2.  It is possible to freely switch
-          between using the ext3 driver and the ext2 driver, as long as the
-          file system has been cleanly unmounted, or e2fsck is run on the file
-          system.
-          To add a journal on an existing ext2 file system or change the
-          behavior of ext3 file systems, you can use the tune2fs utility ("man

-        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.
