config SDFAT_FS

	tristate "sdFAT fs support"

	default y

	select NLS

	select NLS_UTF8

	select NLS_CODEPAGE_437

	select NLS_ISO8859_1

	help

	  If you want to use the sdFAT file system, then you must say Y or M

	  here to inlucde sdFAT support.

	  sdFAT is unified FAT-based file system which supports not only fat12/

	  16/32 with vfat but also exfat. sdFAT supports winnt short-name rule.

	  (winnt: emulate the Windows NT rule for display/create.)



	  To compile this as a module, choose M here: the module will be called

	  sdfat_core and sdfat_fs.



config SDFAT_DELAYED_META_DIRTY

	bool "Enable delayed metadata dirty"

	default y

	depends on SDFAT_FS

	help

	  If you enable this feature, metadata(FAT/Directory entry) is updated

	  by flush thread.



config SDFAT_SUPPORT_DIR_SYNC

	bool "Enable supporting dir sync"

	default n

	depends on SDFAT_FS

	help

	  If you enable this feature, the modification for directory operation

	  is written to a storage at once.



config SDFAT_DEFAULT_CODEPAGE

	int "Default codepage for sdFAT"

	default 437

	depends on SDFAT_FS

	help

	  This option should be set to the codepage of your sdFAT filesystems.



config SDFAT_DEFAULT_IOCHARSET

	string "Default iocharset for sdFAT"

	default "utf8"

	depends on SDFAT_FS

	help

	  Set this to the default input/output character set you'd

	  like sdFAT to use. It should probably match the character set

	  that most of your sdFAT filesystems use, and can be overridden

	  with the "iocharset" mount option for sdFAT filesystems.



config SDFAT_CHECK_RO_ATTR

	bool "Check read-only attribute"

	default n

	depends on SDFAT_FS



config SDFAT_ALIGNED_MPAGE_WRITE

	help

	  Set this to the default string for SELinux label.
