From 49fd524f95cb4cc699d435e0ebb08b1c6220da6d Mon Sep 17 00:00:00 2001 From: Jens Axboe Date: Wed, 16 Apr 2014 10:57:18 -0600 Subject: bsg: update check for rq based driver for blk-mq bsg currently checks ->request_fn to check whether a queue can handle struct request. But with blk-mq, we don't have a request_fn yet are request based. Add a queue_is_rq_based() helper and use that in bsg, I'm guessing this is not the last place we need to update for this. Besides, it better explains what is being checked.
