Subject: [PATCH 11/19] blk-wbt: open code wbt_queue_depth_changed in wbt_init
Date: Wed,  1 Feb 2023 14:41:15 +0100	[thread overview]
Message-ID: <20230201134123.2656505-12-hch@lst.de> (raw)
In-Reply-To: <20230201134123.2656505-1-hch@lst.de>

wbt_queue_depth_changed just updates a field and calls another function.
Open code it in wbt_init, so that the local queue variable can be used
instead of the one stored in the rq_qos.  This will allow delaying that
rq_qos->queue assignment in a subsequent patch.
