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

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

From: Patrick J. LoPresti <lopresti@gmail.com>

commit 9b00c64318cc337846a7a08a5678f5f19aeff188 upstream.

Running "cat /proc/mounts" fails to display the "lookupcache" option.
This oversight cost me a bunch of wasted time recently.

The following simple patch fixes it.
