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?
Thanks,
Tao

Wim didn't send a pull request in this release cycle. 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.
