Hi Wim, Not sure if I looked at the wrong repository/branch, and looks like the patch is not included. Do you have any further suggestions? Or should I send out v2 in case it's missed?

I have the patch in my watchdog-next branch, so he'll hopefully pick it up from there at some point. Resending the patch would just create noise at this point; please don't do that. Guenter
