Description

using the latest docker/cli to test --device-write-bps does not work. It can't limit the IO bps.

Reproduce

docker run --device-read-bps /dev/sda2:10M busybox sh -c 'dd if=/dev/zero of=/tmp.img bs=10M count=10 oflag=direct conv=fsync'

Expected behavior

the speed of "dd" should be around 10M/s
