  * Basic tests for getxattr(2) and make sure getxattr(2) handles error

  *
- * There are 4 test cases:
+ * There are 3 test cases:
+ *
  * 1. Get an non-existing attribute,
  *    getxattr(2) should return -1 and set errno to ENODATA
  * 2. Buffer size is smaller than attribute value size,
  *    getxattr(2) should return -1 and set errno to ERANGE
- * 3. Get attribute, getxattr(2) should succeed
- * 4. Verify the attribute got by getxattr(2) is same as the value we set
+ * 3. Get attribute, getxattr(2) should succeed, and the attribute got by
+ *    getxattr(2) should be same as the value we set
