+config UBIFS_FS

+	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'.

+	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.
