  "message": "writeback: expose the bdi_wq workqueue\n\nThere are cases where userland wants to tweak the priority and\naffinity of writeback flushers.  Expose bdi_wq to userland by setting\nWQ_SYSFS.  It appears under /sys/bus/workqueue/devices/writeback/ and\nallows adjusting maximum concurrency level, cpumask and nice level.\n\nSigned-off-by: Tejun Heo \u003ctj@kernel.org\u003e\nCc: Jens Axboe \u003caxboe@kernel.dk\u003e\nCc: Fengguang Wu \u003cfengguang.wu@intel.com\u003e\nCc: Jeff Moyer \u003cjmoyer@redhat.com\u003e\nCc: Kay Sievers \u003ckay.sievers@vrfy.org\u003e\nCc: Greg Kroah-Hartman \u003cgregkh@linuxfoundation.org\u003e\n",
