27# DESCRIPTION:
28#       Perform file operations in idmapped folder in user namespace,
29#       then check the owner in its base.
30#
31#
32# STRATEGY:
33#       1. Create folder "idmap_test"
34#       2. Idmap the folder to "idmap_dest"
35#       3. Perform file operations in the idmapped folder in the user
36#          namespace having the same idmap info as the idmapped mount
37#       4. Verify the owner of entries under the base folder "idmap_test"
