There are lots of rumors around about the benefit of changing io-schedulers for OSD disks.
Even some benchmarks can be found, but they are all more than a few years old. 
Since ceph is moving forward with quite a pace, i am wondering what the common practice is to use as io-scheduler on OSD's.

And since blk-mq is around these days, are the multi-queue schedules already being used in production clusters?
