Change some netfilter tunables to __read_mostly. Also fixed some incorrect file reference comments while I was in there. (this will be my last __read_mostly patch unless someone points out something else that needs it) Signed-off-by: Brian Haley <brian.haley@hp.com> Acked-by: Patrick McHardy <kaber@trash.net> Signed-off-by: David S.
