When running "wic rm" on a docker container which use the aufs as a
storage driver, the wic would raise a exception since both
SEEK_DATA/HOLE and FIEMAP are not supported on aufs filesystem. This
patch series fixes this problem by introducing a new class to fall
back to the standard copy in this case.

Kevin Hao (3):
  wic/filemap: Drop the unused block_is_unmapped()
  wic/filemap: Drop the unused get_unmapped_ranges()
  wic/filemap: Fall back to standard copy when no way to get the block
    map
