-	  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.
