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.
config F2FS_STAT_FS
bool "F2FS Status Information"
depends on F2FS_FS
default y
help
/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 filesystem 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 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
groups beyond the owner/group/world scheme.
If you don't know what Access Control Lists are, say N
config F2FS_FS_SECURITY
bool "F2FS Security Labels"
depends on F2FS_FS_XATTR
help
Security labels provide an access control facility to support Linux
Security Models (LSMs) accepted by AppArmor, SELinux, Smack and TOMOYO
Linux. This option enables an extended attribute handler for file
security labels in the f2fs filesystem, so that it requires enabling
the extended attribute support in advance. In particular you need this
option if you use the setcap command to assign initial process capabi-
lities to executables (the security.* extended attributes).
If you are not using a security module, say N.
config F2FS_CHECK_FS
bool "F2FS consistency checking feature"
depends on F2FS_FS
help
Enables BUG_ONs which check the filesystem consistency in runtime.
If you want to improve the performance, say N.
config F2FS_FS_ENCRYPTION
bool "F2FS Encryption"
depends on F2FS_FS
select FS_ENCRYPTION
help
This kconfig symbol is deprecated; now it just selects
FS_ENCRYPTION. Use CONFIG_FS_ENCRYPTION=y in new config
files.
config F2FS_IO_TRACE
bool "F2FS IO tracer"
depends on F2FS_FS
depends on FUNCTION_TRACER
help
F2FS IO trace is based on a function trace, which gathers process
information and block IO patterns in the filesystem level.
If unsure, say N.
config F2FS_FAULT_INJECTION
bool "F2FS fault injection facility"
depends on F2FS_FS
help
Test F2FS to inject faults such as ENOMEM, ENOSPC, and so on.
If unsure, say N.
config F2FS_FS_COMPRESSION
bool "F2FS compression feature"
depends on F2FS_FS
help
Enable filesystem-level compression on f2fs regular files,
multiple back-end compression algorithms are supported.
config F2FS_FS_LZO
bool "LZO compression support"
depends on F2FS_FS_COMPRESSION
select LZO_COMPRESS
select LZO_DECOMPRESS
default y
help
Support LZO compress algorithm, if unsure, say Y.
config F2FS_FS_LZ4
bool "LZ4 compression support"
depends on F2FS_FS_COMPRESSION
select LZ4_COMPRESS
select LZ4_DECOMPRESS

help
Support LZ4 compress algorithm, if unsure, say Y.
config F2FS_FS_ZSTD
bool "ZSTD compression support"

help
