2.6.32-stable review patch. If anyone has any objections, please let us know.

------------------


From: Christoph Hellwig <hch(a)infradead.org>

commit 9b00f30762fe9f914eb6e03057a616ed63a4e8ca upstream

A "df" run on an NFS client of an exported XFS file system reports
the wrong information for "available" blocks. When a block quota is
enforced, the amount reported as free is limited by the quota, but
the amount reported available is not (and should be).
