Hi Juergen,
I’m sorry but I don’t see when the parameter is used, in patch 4 we have this
call:
line 2344:
if (delayed_requests) {
list_for_each_entry(conn, &connections, list) {
struct delayed_request *req, *tmp;
list_for_each_entry_safe(req, tmp,
&conn->delayed, list)
call_delayed(conn, req);
}
}
But call_delayed is still this one:
Line 273:
static void call_delayed(struct connection *conn, struct delayed_request *req)
{
if (req->func(req)) {
undelay_request(req);
talloc_set_destructor(req, NULL);
}
}
Am I missing something?
Cheers,
Luca
