	  F2FS is based on Log-structured File System (LFS), which supports
	  versatile "flash-friendly" features. The design has been focused on
	  addressing the fundamental issues in LFS, which are snowball effect
	  of wandering tree and high cleaning overhead.

	  Since flash-based storages show different characteristics according to
	  the internal geometry or flash memory management schemes aka FTL, F2FS
	  and tools support various parameters not only for configuring on-disk
	  layout, but also for selecting allocation and cleaning algorithms.

	  If unsure, say N.

config F2FS_STAT_FS

	help
	  /sys/kernel/debug/f2fs/ contains information about all the partitions
	  mounted as f2fs. Each file shows the whole f2fs information.

	  /sys/kernel/debug/f2fs/status includes:
	    - major filesystem information managed by f2fs currently
	    - average SIT information about whole segments
	    - current memory footprint consumed by f2fs.

config F2FS_FS_XATTR

	  Extended attributes are name:value pairs associated with inodes by

config F2FS_FS_SECURITY
	bool "F2FS Security Labels"
	depends on F2FS_FS_XATTR
	help
	  Security labels provide an access control facility to support Linux
	  Security Models (LSMs) accepted by AppArmor, SELinux, Smack and TOMOYO
	  Linux. This option enables an extended attribute handler for file
	  security labels in the f2fs filesystem, so that it requires enabling
	  the extended attribute support in advance. In particular you need this
	  option if you use the setcap command to assign initial process capabi-
	  lities to executables (the security.* extended attributes).

	  If you are not using a security module, say N.
