how do I setup XFS to not null files after a bad shutdown?

The last time our UPS failed, no files were corrupted because:

- the NFS exports are setup with the sync flag, as recommended,

- [to be verified] Samba shares filesystems with "strict sync" and
  "sync always" options,

For local files, use the sync attribute (chattr +S) to be sure that file
contents are flushed on disk. This is usefull when files are frequently

Is there any way to set this for an entire filesystem? Also, there must be a performance hit from doing this, right?
