  "message": "workqueue: WORKER_REBIND is no longer necessary for busy rebinding\n\nBecause the old unbind/rebinding implementation wasn\u0027t atomic w.r.t.\nGCWQ_DISASSOCIATED manipulation which is protected by\nglobal_cwq-\u003elock, we had to use two flags, WORKER_UNBOUND and\nWORKER_REBIND, to avoid incorrectly losing all NOT_RUNNING bits with\nback-to-back CPU hotplug operations; otherwise, completion of\nrebinding while another unbinding is in progress could clear UNBIND\nprematurely.\n\nNow that both unbind/rebinding are atomic w.r.t. GCWQ_DISASSOCIATED,\nthere\u0027s no need to use two flags.  Just one is enough.  Don\u0027t use\nWORKER_REBIND for busy rebinding.\n\ntj: Updated description.\n\nSigned-off-by: Lai Jiangshan \u003claijs@cn.fujitsu.com\u003e\nSigned-off-by: Tejun Heo \u003ctj@kernel.org\u003e\n",
