Thanks Julia.
A few suggestions & questions:
Perhaps the script should go into scripts/coccinelle/
so that future cases could be caught by the robot
and commit message referenced by the patch instances.
Can you please compile the files modified using the
appropriate defconfig/allyesconfig and show the
movement from data to const by using
$ size <object>.new/old
and include that in the changelogs (maybe next time)?
Is it possible for a rule to trace the instances where
an address of a struct or struct member is taken by
locally defined and declared function call where the
callee does not modify any dereferenced object?
ie:
struct foo {
int bar;
char *baz;
};
struct foo qux[] = {
{ 1, "description 1" },
{ 2, "dewcription 2" },
[ n, "etc" ]...,
};
void message(struct foo *msg)
{
printk("%d %s\n", msg->bar, msg->baz);
}
where some code uses
message(qux[index]);
So could a coccinelle script change:
struct foo qux[] = { to const struct foo quz[] = {
and
void message(struct foo *msg) to void message(const struct foo *msg)
