Subject: [PATCH] blkcg: s/RQ_QOS_CGROUP/RQ_QOS_LATENCY/
References: bsc#1156419,jsc#SLE-8281
Git-commit: beab17fc2a507e85dd18b3cef83820c5770c5f34
Patch-mainline: v5.4-rc1

io.weight is gonna be another rq_qos cgroup mechanism.  Let's rename
RQ_QOS_CGROUP which is being used by io.latency to RQ_QOS_LATENCY in
preparation.
