Date: Tue Jun 09 2009 - 06:17:32 EST


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

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

From: Florian Westphal <fw@xxxxxxxxx>

[ Upstream commit 5b5f792a6a9a2f9ae812d151ed621f72e99b1725 ]

typo -- pkt_dev->nflows is for stats only, the number of concurrent
flows is stored in cflows.
