Thomas Gleixner 007d84287c sched/mmcid: Drop per CPU CID immediately when switching to per task mode ... When a exiting task initiates the switch from per CPU back to per task mode, it has already dropped its CID and marked itself inactive. But a leftover from an earlier iteration of the rework then reassigns the per CPU CID to the exiting task with the transition bit set. That's wrong as the task is already marked CID inactive, which means it is inconsistent state. It's harmless because the CID is marked in transit and therefore dropped back into the pool when the exiting task schedules out either through preemption or the final schedule(). Simply drop the per CPU CID when the exiting task triggered the transition.
