This l3mdev_ops structure is only stored in the l3mdev_ops field of a net_device structure. This field is declared const, so the l3mdev_ops structure can be declared as const also. Additionally drop the __read_mostly annotation. The semantic patch that adds const is as follows: (http://coccinelle.lip6.fr/) // <smpl> @r disable optional_qualifier@ identifier i; position p; @@ static struct l3mdev_ops i@p = { ... }; @ok@ identifier r.i; struct net_device *e; position p; @@ e->l3mdev_ops = &i@p; @bad@ position p != {r.p,ok.p}; identifier r.i; struct l3mdev_ops e; @@ e@i@p @depends on !bad disable optional_qualifier@ identifier r.i; @@ static +const struct l3mdev_ops i = { ... }; // </smpl> The effect on the layout of the .o file is shown by the following output of the size command, first before then after the transformation: text data bss dec hex filename 7364 466 52 7882 1eca drivers/net/ipvlan/ipvlan_main.o 7412 434 52 7898 1eda drivers/net/ipvlan/ipvlan_main.o Signed-off-by: Julia Lawall <Julia.Lawall@lip6.fr> Signed-off-by: David S.
