The xattr handler prototypes were sanitized with the idea being that the same handlers could be used for multiple methods. The result of this was the inode type was changes to a dentry, and both the get() and set() hooks had a handler_flags argument added. The list() callback was similiarly effected but no autoconf check was added because we do not use the list() callback.
