This is used for computing the scheduling dependencies:
Leaf filters check if the header could be matched, similar to the can_match() method; if it does they return 1, and 0 otherwise. Intermediate nodes always return 0.
This is used to build precise dependencies between the suppliers and the leaf of the filters that accept that event. Notice that only the nodes doing scheduling recurse through the list, so in configurations that do no require scheduling the recursion stops fairly soon.

Returns 0 if an event with that header could never be accepted. This can used by the suppliers to filter out consumers that couldn't possibly be interested in their events. The rt_info and
