+ UBIFS is a file system for flash devices which works on top of UBI.

+ This option enables support of extended attributes.

+ 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.

+ Zlib compresses better than LZO but it is slower. Say 'Y' if unsure.

+config UBIFS_FS_DEBUG
+ bool "Enable debugging support"
+ depends on UBIFS_FS
+ select DEBUG_FS
+ 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.
