[PATCH] netfilter: have r->cost != 0 case work

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Commit v2.6.19-rc1~1272^2~41 tells us that r->cost != 0 can happen when
a running state is saved to userspace and then reinstated from there.

Make sure that priv is initialized with some values when that happens.
