I'm objecting to this and the preceding patch until there's a proper explanation of why device-mapper should be excluded from the backport. I've attached an alternate version of this patch that has the device-mapper part restored. While I haven't tested this (don't know what the test case would be) I think it is rather more likely to be a correct backport to 4.4. Ben. -- Ben Hutchings Software Developer, Codethink Ltd.
