From 44e8c2bff80bb384a608406009948f90a78bf8a3 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Fri, 16 Jun 2017 18:15:25 +0200 Subject: blk-mq: refactor blk_mq_sched_assign_ioc blk_mq_sched_assign_ioc now only handles the assigned of the ioc if the schedule needs it (bfq only at the moment). The caller to the per-request initializer is moved out so that it can be merged with a similar call for the kyber I/O scheduler.
