This test exercises the problem with unwritten and delayed extents in ext4 extent status tree where we might in some cases lose a block worth of data. Even though this was a ext4 specific problem the reproducer can be easily run on any file system so let's do that just in case. This test exercises the problem fixed in kernel with commit "ext4: Fix data corruption caused by unwritten and delayed extents" Signed-off-by: Lukas Czerner <lczerner@redhat.com> Reviewed-by: Eryu Guan <eguan@redhat.com> Signed-off-by: Dave Chinner <david@fromorbit.com>
