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