Joe/All,

Acknowledged. I apologize for the inconvenience there -- I was
unfamiliar with that API until receiving your email. I'll hold on
additional uploads until other reviewers have had time to take a
look, but I do plan on leveraging the ftrace API instead of just
using __func__ and %s in my printk strings in the upcoming 'v2'
patchset.

Thanks for your feedback,
Geordan
