From d34849913819a5e0cbfbe724dbe79df89278c524 Mon Sep 17 00:00:00 2001 From: Jens Axboe Date: Fri, 13 Jan 2017 14:43:58 -0700 Subject: blk-mq-sched: allow setting of default IO scheduler Add Kconfig entries to manage what devices get assigned an MQ scheduler, and add a blk-mq flag for drivers to opt out of scheduling. The latter is useful for admin type queues that still allocate a blk-mq queue and tag set, but aren't use for normal IO.
