From e5f7195931f72fedf64af1deb6193c8e0acc26b3 Mon Sep 17 00:00:00 2001 From: "Patrick J. LoPresti" Date: Tue, 10 Aug 2010 17:28:01 -0400 Subject: nfs: Add "lookupcache" to displayed mount options 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.
