- UBIFS is a file system for flash devices which works on top of UBI.
- config UBIFS_FS_ADVANCED_COMPR
- bool "Advanced compression options"
- depends on UBIFS_FS
- help
- This option allows to explicitly choose which compressions, if any,
- are enabled in UBIFS. Removing compressors means inability to read
- existing file systems.
- If unsure, say 'N'.

- LZO compressor is generally faster than zlib but compresses worse.
- Say 'Y' if unsure.
- config UBIFS_FS_ZLIB
- bool "ZLIB compression support" if UBIFS_FS_ADVANCED_COMPR
- depends on UBIFS_FS
- default y
- help
- Zlib compresses better than LZO but it is slower. Say 'Y' if unsure.

- select KALLSYMS
- help
- This option enables UBIFS debugging support. It makes sure various
- assertions, self-checks, debugging messages and test modes are compiled
- in (this all is compiled out otherwise). Assertions are light-weight
- and this option also enables them. Self-checks, debugging messages and
- test modes are switched off by default. Thus, it is safe and actually
- recommended to have debugging support enabled, and it should not slow
- down UBIFS. You can then further enable / disable individual debugging
- features using UBIFS module parameters and the corresponding sysfs
- interfaces.
