From 344e9ffcbd1898e1dc04085564a6e05c30ea8199 Mon Sep 17 00:00:00 2001 From: Jens Axboe Date: Thu, 15 Nov 2018 12:22:51 -0700 Subject: block: add queue_is_mq() helper Various spots check for q->mq_ops being non-NULL, but provide a helper to do this instead. Where the ->mq_ops != NULL check is redundant, remove it. Since mq == rq-based now that legacy is gone, get rid of the queue_is_rq_based() and just use queue_is_mq() everywhere.
