marker: preserve previous dirty flag during update txn
In case if dir has become dirty because of brick crash, this dirty flag on disk was getting reset in the next update txn. This patch now gets the dirty flag before setting the flag in the update txn and if this value is dirty, it keeps the flag dirty, so that inspect_directory can fix the dirty dir Change-Id: Iab2c343dbe19bd3b291adbfeebe6d9785b6bb9e3 BUG: 1251454 Signed-off-by: vmallika <vmallika@redhat.com> Reviewed-on: http://review.gluster.org/12032 Tested-by: NetBSD Build System <jenkins@build.gluster.org> Reviewed-by: Raghavendra G <rgowdapp@redhat.com>
