- depends on BLOCK
- help
- 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.

- /sys/kernel/debug/f2fs/ contains information about all the partitions
- mounted as f2fs. Each file shows the whole f2fs information.
- /sys/kernel/debug/f2fs/status includes:
- - major file system information managed by f2fs currently
- - average SIT information about whole segments
- - current memory footprint consumed by f2fs.
- config F2FS_FS_XATTR
- bool "F2FS extended attributes"
- depends on F2FS_FS
- default y
- help
- Extended attributes are name:value pairs associated with inodes by
- the kernel or by users (see the attr(5) manual page, or visit
- <http://acl.bestbits.at/> for details).
- If unsure, say N.
- config F2FS_FS_POSIX_ACL
- bool "F2FS Access Control Lists"
- depends on F2FS_FS_XATTR
- select FS_POSIX_ACL
- default y
- help
- Posix Access Control Lists (ACLs) support permissions for users and
- gourps beyond the owner/group/world scheme.
- To learn more about Access Control Lists, visit the POSIX ACLs for
- Linux website <http://acl.bestbits.at/>.
- If you don't know what Access Control Lists are, say N
