  "message": "workqueue: convert worker_pool-\u003eworker_ida to idr and implement for_each_pool_worker()\n\nMake worker_ida an idr - worker_idr and use it to implement\nfor_each_pool_worker() which will be used to simplify worker rebinding\non CPU_ONLINE.\n\npool-\u003eworker_idr is protected by both pool-\u003emanager_mutex and\npool-\u003elock so that it can be iterated while holding either lock.\n\n* create_worker() allocates ID without installing worker pointer and\n  installs the pointer later using idr_replace().  This is because\n  worker ID is needed when creating the actual task to name it and the\n  new worker shouldn\u0027t be visible to iterations before fully\n  initialized.\n\n* In destroy_worker(), ID removal is moved before kthread_stop().\n  This is again to guarantee that only fully working workers are\n  visible to for_each_pool_worker().\n\nSigned-off-by: Tejun Heo \u003ctj@kernel.org\u003e\nReviewed-by: Lai Jiangshan \u003claijs@cn.fujitsu.com\u003e\n",
