   1config F2FS_FS

   4        help
   5          F2FS is based on Log-structured File System (LFS), which supports
   6          versatile "flash-friendly" features. The design has been focused on
   7          addressing the fundamental issues in LFS, which are snowball effect
   8          of wandering tree and high cleaning overhead.
   9
  10          Since flash-based storages show different characteristics according to
  11          the internal geometry or flash memory management schemes aka FTL, F2FS
  12          and tools support various parameters not only for configuring on-disk
  13          layout, but also for selecting allocation and cleaning algorithms.

  15          If unsure, say N.

  22          /sys/kernel/debug/f2fs/ contains information about all the partitions
  23          mounted as f2fs. Each file shows the whole f2fs information.
  24
  25          /sys/kernel/debug/f2fs/status includes:
  26            - major filesystem information managed by f2fs currently
  27            - average SIT information about whole segments
  28            - current memory footprint consumed by f2fs.

  33        default y
  34        help
  35          Extended attributes are name:value pairs associated with inodes by
  36          the kernel or by users (see the attr(5) manual page, or visit
  37          <http://acl.bestbits.at/> for details).

  47          Posix Access Control Lists (ACLs) support permissions for users and
  48          gourps beyond the owner/group/world scheme.

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

  55config F2FS_FS_SECURITY
  56        bool "F2FS Security Labels"
  57        depends on F2FS_FS_XATTR
  58        help
  59          Security labels provide an access control facility to support Linux
  60          Security Models (LSMs) accepted by AppArmor, SELinux, Smack and TOMOYO
  61          Linux. This option enables an extended attribute handler for file
  62          security labels in the f2fs filesystem, so that it requires enabling
  63          the extended attribute support in advance.
  64
  65          If you are not using a security module, say N.

  67config F2FS_CHECK_FS

  71          Enables BUG_ONs which check the filesystem consistency in runtime.
