From: Erez Zadok <[EMAIL PROTECTED]>
Unionfs needs a special fan-out version of fsstack_copy_attr_all. A
single-level stackable file systems such as eCryptfs can therefore use a
simplified fsstack_copy_attr_all function; remove its 3rd argument, which
was never used by eCryptfs and was only used by Unionfs.
