![]() list_for_each_safe is able to handle an empty list. The only effect of avoiding the loop is not initializing the index variable. Drop list_empty tests in cases where these variables are not used. The semantic patch that makes this change is as follows: (http://coccinelle.lip6.fr/) <smpl> @@ expression x,e; iterator name list_for_each_safe; statement S; identifier i,j; @@ -if (!(list_empty(x))) { list_for_each_safe(i,j,x) S - } ... when != i when != j ( i = e; | ? j = e; ) </smpl> Signed-off-by: Julia Lawall <Julia.Lawall@inria.fr> Acked-by: Edward Cree <ecree@solarflare.com> Signed-off-by: David S.
