This change is causing tuxera rename test failure with acls enabled.

/root/pjd-fstest-20080816/tests/rename/10.t  (Wstat: 0 Tests: 188 Failed: 6)
   Failed tests:  65, 71, 74, 77, 79-80
The comment in namei says:
"  If d_revalidate returned 0 attempt to invalidate  the dentry 
otherwise d_revalidate is asking us
  to return a fail status." I guess we need to return 0 in the case of 
rename.
Need more closer look at this patch.
