-          messages at level 1 while the misbehaviour was occurring. Level 2

+          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.
