  "message": "block: add sysfs knob for turning off disk entropy contributions\n\nThere are two reasons for doing this:\n\n- On SSD disks, the completion times aren\u0027t as random as they\n  are for rotational drives. So it\u0027s questionable whether they\n  should contribute to the random pool in the first place.\n\n- Calling add_disk_randomness() has a lot of overhead.\n\nThis adds /sys/block/\u003cdev\u003e/queue/add_random that will allow you to\nswitch off on a per-device basis. The default setting is on, so there\nshould be no functional changes from this patch.\n\nSigned-off-by: Jens Axboe \u003cjaxboe@fusionio.com\u003e\n",
