sysctls go away on network interfaces being removed. Which includes
not only ppp et.al., but all sorts of tunnels, etc. IOW, you can
wait for it to happen - in a lot of setups it will. And in case of
e.g. ipv4 sysctls we are talking about >2Kb allocated on amd64, so
kmalloc() will pick full pages for each (per-interface) set of sysctls...
Thanks for the info, Al. Reassigning.
