It is reported by sashiko [1] that nr_deadline_tasks\ncan currently be modified by inc_dl_tasks_cs() under rq->lock and\nby cpuset_attach() under cpuset_mutex. So if both updates happen\nsimultaneously, the nr_deadline_tasks variable can be corrupted leading\nto incorrect operations down the road.\n\nFix that by changing its type to atomic_t so that nr_deadline_tasks\nare always atomically updated. This fix patch is a low hanging fruit.\nIt can handle some of the races between a concurrent sched_setscheduler()\nand cpuset_can_attach()/cpuset_attach() calls, but not all of them like\nthe other issue raised by sashiko [2]. This will be handled hopefully\nin a future follow up patch.\n\n[1] https://sashiko.dev/#/patchset/20260626181923.133658-1-longman%40redhat.com\n[2] https://sashiko.dev/#/patchset/20260630033344.352702-1-longman%40redhat.com"
