Subject[ 071/127] NFS: Fix a problem with the legacy binary mount code
Date
3.0-stable review patch.  If anyone has any objections, please let me know.

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

From: Trond Myklebust <Trond.Myklebust@netapp.com>

commit 872ece86ea5c367aa92f44689c2d01a1c767aeb3 upstream.

Apparently, am-utils is still using the legacy binary mountdata interface,
and is having trouble parsing /proc/mounts due to the 'port=' field being
incorrectly set.

The following patch should fix up the regression.
