config F2FS_FS

	tristate "F2FS filesystem support (EXPERIMENTAL)"

	help

	  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

	bool "F2FS Status Information"

	depends on F2FS_FS && DEBUG_FS

	default y

	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 file system information managed by f2fs currently

	    - average SIT information about whole segments

	    - current memory footprint consumed by f2fs.



config F2FS_FS_XATTR

	bool "F2FS extended attributes"

	depends on F2FS_FS

	default y

	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).



	  If unsure, say N.



config F2FS_FS_POSIX_ACL

	bool "F2FS Access Control Lists"

	depends on F2FS_FS_XATTR

	select FS_POSIX_ACL

	default y

	help

	  Posix Access Control Lists (ACLs) support permissions for users and

	  gourps beyond the owner/group/world scheme.



	  To learn more about Access Control Lists, visit the POSIX ACLs for

	  Linux website <http://acl.bestbits.at/>.



	  If you don't know what Access Control Lists are, say N
