marker: preserve previous dirty flag during update txn
This is a backport of http://review.gluster.org/#/c/12032/ In case if dir has become dirty because of crash, this dirty flag on disk was getting reset in the next update txn. This patch now gets the dirty flag before setting in the update txn and it the 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> Change-Id: I10b81e5c0d9ffa00082171e295199d924a81ee0e BUG: 1257441 Signed-off-by: vmallika <vmallika@redhat.com> Reviewed-on: http://review.gluster.org/12037 Tested-by: Gluster Build System <jenkins@build.gluster.com> Tested-by: NetBSD Build System <jenkins@build.gluster.org> Reviewed-by: Kaushal M <kaushal@redhat.com>
