      "message": "block: strict rq_affinity\n\nSome systems benefit from completions always being steered to the strict\nrequester cpu rather than the looser \"per-socket\" steering that\nblk_cpu_to_group() attempts by default. This is because the first\nCPU in the group mask ends up being completely overloaded with work,\nwhile the others (including the original submitter) has power left\nto spare.\n\nAllow the strict mode to be set by writing \u00272\u0027 to the sysfs control\nfile. This is identical to the scheme used for the nomerges file,\nwhere \u00272\u0027 is a more aggressive setting than just being turned on.\n\necho 2 \u003e /sys/block/\u003cbdev\u003e/queue/rq_affinity\n\nCc: Christoph Hellwig \u003chch@infradead.org\u003e\nCc: Roland Dreier \u003croland@purestorage.com\u003e\nTested-by: Dave Jiang \u003cdave.jiang@intel.com\u003e\nSigned-off-by: Dan Williams \u003cdan.j.williams@intel.com\u003e\nSigned-off-by: Jens Axboe \u003cjaxboe@fusionio.com\u003e\n"
