From 5a22e2bf44fb311e5a6bfec6ed5680199d6e162a Mon Sep 17 00:00:00 2001 From: Israel Rukshin Date: Wed, 18 Oct 2017 12:38:25 +0000 Subject: [PATCH] nvme-fc: Add BLK_MQ_F_NO_SCHED flag to admin tag set Since commit b86dd81 "block: get rid of blk-mq default scheduler choice Kconfig entries", when setting nr_hw_queues to 1 the admin tag set uses mq-deadline scheduler. This flag is useful for admin queues that aren't used for normal IO.
