DEBUG can be enabled by other kernel option and should provide just more 
debugging functionality. But you are adding non-debug functionality 
under #ifdef DEBUG, which basically is "new experimental untested 
feature".

Better way for "experimental feature" would be introduction of other 
kconfig switch or probably runtime module option...
