  "message": "cfq-iosched: fix the setting of IOPS mode on SSDs\n\nA previous commit wanted to make CFQ default to IOPS mode on\nnon-rotational storage, however it did so when the queue was\ninitialized and the non-rotational flag is only set later on\nin the probe.\n\nAdd an elevator hook that gets called off the add_disk() path,\nat that point we know that feature probing has finished, and\nwe can reliably check for the various flags that drivers can\nset.\n\nFixes: 41c0126b (\"block: Make CFQ default to IOPS mode on SSDs\")\nTested-by: Romain Francoise \u003cromain@orebokech.com\u003e\nSigned-off-by: Jens Axboe \u003caxboe@fb.com\u003e\n",
