Hmm. This is definitely an improvement, but at somepoint we may want
to drop all of the __func__ usage as the dynamic debug system can
provide back traces which obviously include this info.
So might need a follow up, though perhaps not pre moving out of staging
as this really isn't important.
Hence, applied.
Thanks,
Jonathan
