https://www.illumos.org/issues/6268
  The zfs diff command presents a description of the changes that have occurred
  to files within a filesystem between two snapshots. If a file is renamed, the
  tool is capable of reporting this, e.g.:
  cd /some/zfs/dataset/subdir
  mv file0 file1
  Will result in a diff record like:
  R        /some/zfs/dataset/subdir/file0  ->  /some/zfs/dataset/subdir/file1
  Unfortunately, it seems that rename detection only uses the base filename to
  determine if a file has been renamed or simply modified. This leads to
  misreporting only the original filename, omitting the more relevant destination
  filename entirely. For example:
  cd /some/zfs/dataset/subdir
  mv file0 ../otherdir/file0
  Will result in a diff entry:
  M        /some/zfs/dataset/subdir/file0
  But it should really emit:
  R        /some/zfs/dataset/subdir/file0  ->  /some/zfs/dataset/otherdir/file0
