Well actually this is not an oversight but some unappropriate tracing
attempt I am afraid. I wanted to add a trace useful for the end-user to
make sure the VFIO reset function was called. Do you forbid that or do
recommend to use another tracing mechanism/level? In the past I tried
dynamic tracing but with module loading mechanism I found it not that handy.
