I would consider making the new sysctl tables const. There is an effort for doing this and it has already lanted in linux-next. So if you base your patch from a recent next release, then it should just work. If you *do* decide to add a const qualifier, then note that you will create a dependency with the sysctl patchset currently in next and that will have to go in before. Best -- Joel Granados
