Oleg, i'd like to make it sure that the role of Gregory Haskins is clear here: he submitted some new infrastructure into the -rt tree, and i reviewed that but found it quite complex and duplicative and suggested him to think about enhancing workqueues with priority properties - which might or might not make sense. It is not the intention of the -rt project to pester any upstream maintainer with -rt issues if that upstream maintainer is not interested in it ... so please just forget about all this if you are not interested in it, we'll sort it out within -rt.
