  3. help
  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. Since flash-based storages show different characteristics according to
  9. the internal geometry or flash memory management schemes aka FTL, F2FS
  10. and tools support various parameters not only for configuring on-disk
  11. layout, but also for selecting allocation and cleaning algorithms.
  12. If unsure, say N.

  20. /sys/kernel/debug/f2fs/status includes:

  22. - average SIT information about whole segments
  23. - current memory footprint consumed by f2fs.

  29. Extended attributes are name:value pairs associated with inodes by
  30. the kernel or by users (see the attr(5) manual page, or visit
