Subject: blk-wbt: open code wbt_queue_depth_changed in wbt_init
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=4e1d91ae876bd12f327340f11a16a1278985e7e1;p=linux.git

blk-wbt: open code wbt_queue_depth_changed in wbt_init

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.
