+config NTFS_FS
+	tristate "NTFS file system support"
+	select BUFFER_HEAD
+	select NLS
+	help
+	  NTFS is the file system of Microsoft Windows NT, 2000, XP and 2003.
+
+	  Saying Y or M here enables read support.  There is partial, but
+	  safe, write support available.  For write support you must also
+	  say Y to "NTFS write support" below.
+
+	  There are also a number of user-space tools available, called
+	  ntfsprogs.  These include ntfsundelete and ntfsresize, that work
+	  without NTFS support enabled in the kernel.
+
+	  This is a rewrite from scratch of Linux NTFS support and replaced
+	  the old NTFS code starting with Linux 2.5.11.  A backport to
+	  the Linux 2.4 kernel series is separately available as a patch
+	  from the project web site.
+
+	  For more information see <file:Documentation/filesystems/ntfs.rst>
+	  and <http://www.linux-ntfs.org/>.
+
+	  To compile this file system support as a module, choose M here: the
+	  module will be called ntfs.
+
+	  If you are not using Windows NT, 2000, XP or 2003 in addition to
+	  Linux on your computer it is safe to say N.
+
+config NTFS_DEBUG
+	bool "NTFS debugging support"
+	depends on NTFS_FS
+	help
+	  If you are experiencing any problems with the NTFS file system, say
+	  Y here.  This will result in additional consistency checks to be
+	  performed by the driver as well as additional debugging messages to
+	  be written to the system log.  Note that debugging messages are
+	  disabled by default.  To enable them, supply the option debug_msgs=1
+	  at the kernel command line when booting the kernel or as an option
+	  to insmod when loading the ntfs module.  Once the driver is active,
+	  you can enable debugging messages by doing (as root):
+	  echo 1 > /proc/sys/fs/ntfs-debug
+	  Replacing the "1" with "0" would disable debug messages.
+
+	  If you leave debugging messages disabled, this results in little
+	  overhead, but enabling debug messages results in very significant
+	  slowdown of the system.
+
+	  When reporting bugs, please try to have available a full dump of
+	  debugging messages while the misbehaviour was occurring.
+
+config NTFS_RW
+	bool "NTFS write support"
+	depends on NTFS_FS
+	depends on PAGE_SIZE_LESS_THAN_64KB
+	help
+	  This enables the partial, but safe, write support in the NTFS driver.
+
+	  The only supported operation is overwriting existing files, without
+	  changing the file length.  No file or directory creation, deletion or
+	  renaming is possible.  Note only non-resident files can be written to
+	  so you may find that some very small files (<500 bytes or so) cannot
+	  be written to.
+
+	  While we cannot guarantee that it will not damage any data, we have
+	  so far not received a single report where the driver would have
+	  damaged someones data so we assume it is perfectly safe to use.
+
+	  Note:  While write support is safe in this version (a rewrite from
+	  scratch of the NTFS support), it should be noted that the old NTFS
+	  write support, included in Linux 2.5.10 and before (since 1997),
+	  is not safe.
+
+	  This is currently useful with TopologiLinux.  TopologiLinux is run
+	  on top of any DOS/Microsoft Windows system without partitioning your
+	  hard disk.  Unlike other Linux distributions TopologiLinux does not
+	  need its own partition.  For more information see
+	  <http://topologi-linux.sourceforge.net/>
+
+	  It is perfectly safe to say N here.
