Mathieu Desnoyers 2840cf02fa sched/membarrier: Call sync_core only before usermode for same mm ... When the prev and next task's mm change, switch_mm() provides the core serializing guarantees before returning to usermode. The only case where an explicit core serialization is needed is when the scheduler keeps the same mm for prev and next.
