I'd have to go through it case by case. But in general unless your proc_handler is proc_dointvec the default strategy routine which does a raw binary copy of your data out will generally do the wrong thing. So especially if your data is jiffies or otherwise needs processing you don't want to use the default strategy routine. Until relatively recently no one was really policing the sysctl interfaces and even now it isn't too serious.
