Thanks, Rosen

I did before the concept of FAM landed in the kernel. Whether or not the 
#ifdef DEBUG is warranted is simply a choice. I prefer to have clean 
separation of functionality and the related data. If the code using the 
data is all conditional under DEBUG define then the data must be as well.

I understand that FAM and compiler support for it has its advantages, 
but this is more churn than gain. The code is functional as is and 
removing #defines for the sake of changing to a FAM seems not justified 
for the advantages which in my opinion are pretty limited in this 
particular case.
