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

+ This option enables support of extended attributes.

+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 inbility to read
+ existing file systems.
+
+ If unsure, say 'N'.

+ LZO compressor is generally faster then zlib but compresses worse.

+ default "0"
+ help
+ This controls the amount of debugging messages produced by UBIFS.
+ If reporting bugs, please try to have available a full dump of the
+ messages at level 1 while the misbehaviour was occurring. Level 2
+ may become necessary if level 1 messages were not enough to find the
+ bug. Generally Level 3 should be avoided.
+
+config UBIFS_FS_DEBUG_CHKS
+ bool "Enable extra checks"
+ depends on UBIFS_FS_DEBUG
+ help
+ If extra checks are enabled UBIFS will check the consistency of its
+ internal data structures during operation. However, UBIFS performance
+ is dramatically slower when this option is selected especially if the
+ file system is large.
