Exiting tasks withoutSCX_OPS_ENQ_EXITING, migration disabled tasks withoutSCX_OPS_ENQ_MIGRATION_DISABLED and tasks on an offline rq skip ops.enqueue()and go straight to the local DSQ. This happens in put_prev_task_scx() afterthe pick has settled on idle, so nothing reschedules the CPU, which idleswith the task queued until an unrelated wakeup lands on it or the watchdogfires.\nscx_mitosis, which sets SCX_OPS_ENQ_LAST without SCX_OPS_ENQ_EXITING, hitthis during mass cgroup teardown: exiting tasks stuck in exit_mmap() forover 40 seconds.\nA task put on the local DSQ runs, as anywhere else. If the SCX_ENQ_LASTenqueue left the task on this CPU's local DSQ, set need_resched on the taskbeing switched in, as proxy_resched_idle() does. resched_curr() would flagthe task being put instead, and __schedule() clears that right after
