I am not using this platform, but just doing some janitorial work with
the checkkconfigsymbols.py script, which Randy Dunlap has pointed out
to me. This "general winter cleaning" really started as a "summer
break clean-up" and just took longer... I am also writing a blog post
summarizing the results of these whole kernel clean-up activities and
I will share it with you once it is published.
