This is a cleanup patch and doesn't change runtime behaviour. It
changes an open coded list traversal to use list_for_each_entry_safe.
Done using the following semantic patch by coccinelle.
@r@
struct list_head* l;
expression e;
identifier m, list_del_init, f;
type T1;
T1* pos;
iterator name list_for_each_entry_safe;
@@
f(...){
+T1* tmp;
<+...
-while(...)
+list_for_each_entry_safe(pos,tmp,l,m)
{
...
-pos = container_of(l,T1,m);
...
-l=e;
<+...
list_del_init(&pos->m)
...+>
}
...+>
}
