In linux kernel since version 2.6.27 (release Date: 2008-10-09)
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.
