  "message": "workqueue: implement per-cwq active work limit\n\nAdd cwq-\u003enr_active, cwq-\u003emax_active and cwq-\u003edelayed_work.  nr_active\ncounts the number of active works per cwq.  A work is active if it\u0027s\nflushable (colored) and is on cwq\u0027s worklist.  If nr_active reaches\nmax_active, new works are queued on cwq-\u003edelayed_work and activated\nlater as works on the cwq complete and decrement nr_active.\n\ncwq-\u003emax_active can be specified via the new @max_active parameter to\n__create_workqueue() and is set to 1 for all workqueues for now.  As\neach cwq has only single worker now, this double queueing doesn\u0027t\ncause any behavior difference visible to its users.\n\nThis will be used to reimplement freeze/thaw and implement shared\nworker pool.\n\nSigned-off-by: Tejun Heo \u003ctj@kernel.org\u003e\n",
