Using dtrace to follow a kernel linked list
...ed list.
For example:
struct list {
struct list *next;
void *data;
};
struct list *list_root;
Assuming I had "list_root" available, but I wanted to know how long
the linked list is, how can I do this in a dtrace probe?
If I had looping constructs, it would be obvious:
int
count_list(struct list *list)
{
int i;
for (i = 0; list != NULL; list = list->next)
++i;
return i;
}
In the dtrace scripting language there are no loop constructs, but is
there a way to add a new provider than can loop?
Thank you,
