From a79050434b45959f397042080fd1d70ffa9bd9df Mon Sep 17 00:00:00 2001 From: Josef Bacik Date: Tue, 3 Jul 2018 09:32:35 -0600 Subject: blk-rq-qos: refactor out common elements of blk-wbt blkcg-qos is going to do essentially what wbt does, only on a cgroup basis. Break out the common code that will be shared between blkcg-qos and wbt into blk-rq-qos.* so they can both utilize the same infrastructure.
