> Currently, we use cleanupBarrierStage when detecting different barrier sync types in
a single sync. This cause a problem that a new `ContextBarrierState` can be created again
if there's following requesters on the way. And those corresponding tasks will fail because
of killing instead of different barrier sync types detected.
