Sounds good, except:

- The name `file-attribute-file-number` doesn't sound right
  because it doesn't return a number.

- I wouldn't use `defsubst` (so it can more easily be modified in the
  future, e.g. in case we add more fields to the attributes or use some
  other representation for attributes).

- I would document it more abstractly, mentioning inode and device
  number only as *examples* of things it might contain.
