| 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. | |
