From 0da73d00ca111a6175825a00d94dbeae185f6d7e Mon Sep 17 00:00:00 2001 From: Minwoo Im Date: Mon, 2 Jul 2018 23:46:43 +0900 Subject: blk-mq: code clean-up by adding an API to clear set->mq_map set->mq_map is now currently cleared if something goes wrong when establishing a queue map in blk-mq-pci.c. It's also cleared before updating a queue map in blk_mq_update_queue_map(). This patch provides an API to clear set->mq_map to make it clear.
