From ff2c56609d9b1f0739ae3a3bfdb78191d01e4192 Mon Sep 17 00:00:00 2001 From: Jens Axboe Date: Mon, 29 Oct 2018 13:07:33 -0600 Subject: blk-mq: provide dummy blk_mq_map_queue_type() helper Doesn't do anything right now, but it's needed as a prep patch to get the interfaces right. While in there, correct the blk_mq_map_queue() CPU type to an unsigned int.
