From 99360b4c18f7675b50d283301d46d755affe75fd Mon Sep 17 00:00:00 2001 From: Mikulas Patocka <mpatocka@redhat.com> Date: Thu, 2 Apr 2009 19:55:39 +0100 Subject: [PATCH] dm: set queue ordered mode Set queue ordered mode. It doesn't really matter what we set here because we don't ever put any requests on the queue. But we need to set something other than QUEUE_ORDERED_NONE so that __generic_make_request passes barrier requests to us.
