    Sorry, Chris - I was being even more than usually stupid.  All you
    need do is overload the return value from file_operations.fsync().
    It currently returns zero on success or negative error.  You can
    just define a return value of "1" to mean that the fs has taken
    care of syncing the directory info and no further action is needed
    at the fs layer.

Seems quite reasonable.  I'm quite keen on ehat approach except it
seems for some filesystems, walking the path is expensive.  How about
a flag in the superblock on whether we do this or not?

That said, it's been pointed out it doesn't actually help in several
cases (link/unlink) for example, so maybe I should forget the whole
thing?
