how did your command line look like? This should work:

  osmfilter input_data.osm --keep="landuse=" -o=output_data.osm

If you do NOT want to include nodes and relations on the base of their own landuse tags, enter this:

  osmfilter input_data.osm --keep-ways="landuse=" --keep-nodes-relations="" -o=output_data.osm
