It is torn down with destroy_workqueue() only\non the init error path; msb_remove() never destroys it. msb_stop() merely\nflushes the queue, and neither msb_data_clear() nor put_disk() free it. As\na result every card insert/remove cycle leaks the workqueue and its\nkworker, exhausting kernel memory over repeated cycles.\n\nDestroy the workqueue in msb_remove() after the disk has been removed and\nthe queue drained."
