Hi Arnd
Thanks for reviewing those patches, and your feedback. I have made the
changes recommended. If these are acceptable, I will build a proper
[PATCH] for submission.Is there anyone in particular that I need to mail
in order that these patches go into the next release?
Here is the updated patch with the changes.
