From b0f455599d0f092abc11aa3daba693be1453d29a Mon Sep 17 00:00:00 2001 From: John Snow Date: Tue, 12 Mar 2019 12:05:49 -0400 Subject: block/dirty-bitmaps: add inconsistent bit Add an inconsistent bit to dirty-bitmaps that allows us to report a bitmap as persistent but potentially inconsistent, i.e. if we find bitmaps on a qcow2 that have been marked as "in use".
