I was looking at how best to do this, when I noticed a few things:
1. 'updated' in set_file_attrs is used to indicate that the file meta- 
data was changed and thus things like --link-dest cannot use a hard- 
link, correct?
2. currently if there are any xattrs on a file, it always sets 'updated'
     --> i don't find sending the xattrs over the wire to be a big  
deal, since they have to rather short on most filesysterms
          however, not making the hard-link is quite costly if the  
file is large, simply because it has an extended attribute
Have I understood this correctly?

If so, the fake-super patch should only set updated=1 if the meta- 
data it writes differs from the old meta-data.

Is this the issue that's blocking xattrs being merged into the trunk?
