From f066a4f6df68f03b565dfe867dde54dfeb26576e Mon Sep 17 00:00:00 2001 From: Rusty Russell Date: Tue, 1 Dec 2009 14:56:44 +1030 Subject: [PATCH] param: don't complain about unused module parameters. Jon confirms that recent modprobe will look in /proc/cmdline, so these cmdline options can still be used.
