It appears that that would require 16 separate test files, each with the appropriate combination of "_require_chattr <letter>".

IMO, _require_chattr <letter> means test cannot run without this, so no use in running it. This is not true for this test. Since this test is expecting empty output its not even hard to change the test. First try silently all the 4 letters. Then iterate of combination of supported subset. -- To unsubscribe from this list: send the line "unsubscribe linux-xfs" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
