Could you be more specific please? We already print uid when dumping
eligible tasks so it is not overly hard to find that information in the
oom report. Well, except when dumping of eligible tasks is disabled. Is
this what you are after?

Please always be specific about usecases in the changelog. A terse
statement that something is useful doesn't tell much very often.

Thanks!
