It is actually not that bad, you can simply wrap it, like Pedro did in

Seems nobody uses the system call...

Ok, so proc_dointvec_jiffies is broken by design and the proposal above
is wrong.

Fortunately most net variables don't need a transformation/state setup,
so only proc_dointvec_jiffies and rtcache_flush needs fixing I think, or
did I miss something?
