From 244c65a3ccaa06fd15cc940315606674d3108b2f Mon Sep 17 00:00:00 2001 From: Ming Lei Date: Sat, 4 Nov 2017 12:39:57 -0600 Subject: blk-mq: move blk_mq_put_driver_tag*() into blk-mq.h We need this helper to put the driver tag for flush rq, since we will not share tag in the flush request sequence in the following patch in case that I/O scheduler is applied.
