We need you to do this, so that any questions by the upstream developers

 OK.  Please report this bug at http://bugzilla.samba.org under product
 'CifsVFS', including the 'oops' message'.  Also mention the page
 http://www.kerneloops.org/search.php?search=shrink_dcache_for_umount_subtree
  which summarises many similar crashes.  Let us know the bug number so we can 
 track it.

Rutger, did you report this upstream?
