   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.

  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.
