Hmm, I'm not sure.  However, if it is done, I think it needs to be done in the
FS code (e.g., NFS needs to be able to add it's special timestamps).

In UFS you could do this by just adding a cache_enter() call to ufs_direnter().
For NFS you would want the post-op attrs from the RPC reply (assuming it includes
attrs for the parent directory).
