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. | |
