  "message": "workqueue: replace get_pwq() with explicit per_cpu_ptr() accesses and first_pwq()\n\nget_pwq() takes @cpu, which can also be WORK_CPU_UNBOUND, and @wq and\nreturns the matching pwq (pool_workqueue).  We want to move away from\nusing @cpu for identifying pools and pwqs for unbound pools with\ncustom attributes and there is only one user - workqueue_congested() -\nwhich makes use of the WQ_UNBOUND conditional in get_pwq().  All other\nusers already know whether they\u0027re dealing with a per-cpu or unbound\nworkqueue.\n\nReplace get_pwq() with explicit per_cpu_ptr(wq-\u003ecpu_pwqs, cpu) for\nper-cpu workqueues and first_pwq() for unbound ones, and open-code\nWQ_UNBOUND conditional in workqueue_congested().\n\nNote that this makes workqueue_congested() behave sligntly differently\nwhen @cpu other than WORK_CPU_UNBOUND is specified.  It ignores @cpu\nfor unbound workqueues and always uses the first pwq instead of\noopsing.\n\nSigned-off-by: Tejun Heo \u003ctj@kernel.org\u003e\nReviewed-by: Lai Jiangshan \u003claijs@cn.fujitsu.com\u003e\n",
