So calling sys_mount_setattr here returns 0 instead of -EINVAL as expected. Ramfs is mounted at "/mnt/B" and does not support idmap mounts. So we can use "/mnt/B" instead of "/mnt/A" to make the test run successfully with the following output: # Starting 1 tests from 1 test cases. # RUN mount_setattr_idmapped.idmap_mount_tree_invalid ... # OK mount_setattr_idmapped.idmap_mount_tree_invalid ok 1 mount_setattr_idmapped.idmap_mount_tree_invalid # PASSED: 1 / 1 tests passed.
