From 6f5ba581c0d3ba0a76fe138123c1c2817ffcbeb1 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Fri, 7 Feb 2014 10:22:37 -0800 Subject: [PATCH] blk-mq: divert __blk_put_request for MQ ops __blk_put_request needs to call into the blk-mq code just like blk_put_request. As we don't have the queue lock in this case both end up calling the same function.
