+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"

+        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
