The _casefold_lsattr_dir function lists all of the file attributes. As result, tests/generic/556.out has an ext4-specific assumption that the test directories will have the Extents attribute. That won't be true for all file systems, and it won't even be true for ext4 file systems that do not have the extents feature enabled.
