Well, it seems nicer than the situation we have now. So I'm certainly
ok with seeing this merged for 2.6.38 (through the security tree?) if
nobody has objections.
It's a bit sad to have another atomic in the open path, but if the
lease people want this and are ok with just the counter (no races?)
then it seems worth it.
