This is a horrible hack to get around the fact that ext3 uses the

do not have similar problems as far as I know.

Under what conditions does ext3 exhibit this behaviour? In EVMS, we have been stacking the b_private field (for many months), and have not seen any problems or have had any problems reported with ext3.
