There are two type of errors that fsync can return.
 EBADF EROFS EINVAL  - these are usage errors.
 EIO ENOSPC EDQUOT   - these are functional failures.

So I would say there *is* something special about those errors, though
it isn't *very* special, and it isn't *just* those errors. EDQUOT should
be included in the list.
