+config F2FS_FS
+ tristate "F2FS filesystem support"
+ depends on BLOCK
+ 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 filesystem 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
+
+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.
+
+ If you are not using a security module, say N.
+
+config F2FS_CHECK_FS
+ bool "F2FS consistency checking feature"
+ depends on F2FS_FS
+ help
+ Enables BUG_ONs which check the filesystem consistency in runtime.
+
+ If you want to improve the performance, say N.
+
+config F2FS_IO_TRACE
+ bool "F2FS IO tracer"
+ depends on F2FS_FS
+ depends on FUNCTION_TRACER
+ help
+ F2FS IO trace is based on a function trace, which gathers process
+ information and block IO patterns in the filesystem level.
+
+ If unsure, say N.
