CONFIG_F2FS_FS: F2FS filesystem support

General informations

The Linux kernel configuration item CONFIG_F2FS_FS has multiple definitions:

F2FS filesystem support (EXPERIMENTAL) found in fs/f2fs/Kconfig

The configuration item CONFIG_F2FS_FS:

Help text

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.

If unsure, say N.
