  "message": "workqueue: skip nr_running sanity check in worker_enter_idle() if trustee is active\n\nworker_enter_idle() has WARN_ON_ONCE() which triggers if nr_running\nisn\u0027t zero when every worker is idle.  This can trigger spuriously\nwhile a cpu is going down due to the way trustee sets %WORKER_ROGUE\nand zaps nr_running.\n\nIt first sets %WORKER_ROGUE on all workers without updating\nnr_running, releases gcwq-\u003elock, schedules, regrabs gcwq-\u003elock and\nthen zaps nr_running.  If the last running worker enters idle\ninbetween, it would see stale nr_running which hasn\u0027t been zapped yet\nand trigger the WARN_ON_ONCE().\n\nFix it by performing the sanity check iff the trustee is idle.\n\nChange-Id: I78c6300647a9e14a5f5f27fee0679d9072481188\nSigned-off-by: Tejun Heo \u003ctj@kernel.org\u003e\nReported-by: \"Paul E.
