The blkio.sectors file is no longer provided; by quick search: https://issues.apache.org/jira/browse/MESOS-9848 so hopefully it's sufficient to test existence of this other file: https://www.kernel.org/doc/html/v5.4/admin-guide/cgroup-v1/blkio-controller.html#common-files-among-various-policies Originally this sub-test was added in 58e40f84.
