Usually, pmus that do, for example, instruction tracing, would only ever be able to have one event per task per cpu (or per perf_event_context). For such pmus it makes sense to disallow creating conflicting events early on, so as to provide consistent behavior for the user. This patch adds a pmu capability that indicates such constraint on event creation.
