And actually these cases use a dummy sysctl blob on the stack to provide the min/max values to proc_dointvec_minmax. And they do it _EXACTLY_ because the extra pointers are for the netns pointer and a pointer to the idev. And any user envisioned can do the same thing, use a trampoline like the existing cases do.
