I've now tested this issue on a vanilla 2.6.11.7 kernel. I only applied
my own patch from the previous post so that I am able to shut down the
computer cleanly. So I did the following:

- boot 2.6.11.7
- create a tap device with 'openvpn --mktun --dev tap0'
- create /etc/netatalk/atalkd.conf with a single line 'tap0'
- launch atalkd, wait.
- stop atalkd.
- destroy tap device with 'openvpn --rmtun --dev tap0'

refcnt was -256, very strange.

Would you consider my patch harmful? I intend using it for now, because
otherwise, my system won't shut down cleanly any more...

Greets, Felix

PS: Please CC replies to me.
PPS: I'm sorry for the multipost (lkml and here), at first I didn't
realize Andrew was directing this thread to linux-netdev
