config F2FS_FS
tristate "F2FS filesystem support (EXPERIMENTAL)"
depends on BLOCK
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.
config F2FS_STAT_FS
bool "F2FS Status Information"
depends on F2FS_FS && DEBUG_FS
default y
/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
Extended attributes are name:value pairs associated with inodes by
the kernel or by users (see the attr(5) manual page, or visit
<> for details).
If unsure, say N.
bool "F2FS Access Control Lists"
depends on F2FS_FS_XATTR
default y
Posix Access Control Lists (ACLs) support permissions for users and
gourps beyond the owner/group/world scheme.

If you don't know what Access Control Lists are, say N
