Subject: [PATCH 06/10] blkcg: s/RQ_QOS_CGROUP/RQ_QOS_LATENCY/
Date: Wed, 10 Jul 2019 13:51:24 -0700
Message-ID: <20190710205128.1316483-7-tj@kernel.org> (raw)
In-Reply-To: <20190710205128.1316483-1-tj@kernel.org>

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.
