+config NTFSPLUS_FS
+	tristate "NTFS+ file system support"
+	select NLS
+	help
+	  NTFS is the file system of Microsoft Windows NT, 2000, XP and 2003.
+	  This allows you to mount devices formatted with the ntfs file system.
+
+	  To compile this as a module, choose M here: the module will be called
+	  ntfsplus.
+
+config NTFSPLUS_DEBUG
+	bool "NTFS+ debugging support"
+	depends on NTFSPLUS_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 NTFSPLUS_FS_POSIX_ACL
+	bool "NTFS+ POSIX Access Control Lists"
+	depends on NTFSPLUS_FS
+	select FS_POSIX_ACL
+	help
+	  POSIX Access Control Lists (ACLs) support additional access rights
+	  for users and groups beyond the standard owner/group/world scheme,
+	  and this option selects support for ACLs specifically for ntfs
+	  filesystems.
+	  NOTE: this is linux only feature. Windows will ignore these ACLs.
+
+	  If you don't know what Access Control Lists are, say N.
