Comment 2 Alexander Viro 2005-09-21 19:12:54 UTC
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...
