From 7d5c3964ccfaace123f7b75e15d38c2650e013d8 Mon Sep 17 00:00:00 2001
From: NeilBrown <neilb@suse.de>
Date: Tue, 17 Nov 2009 13:15:32 +1100
Subject: [PATCH] Change default metadata from 0.90 to 1.1

1.1 is more flexible in a number of ways and is safer.
0.90 is still fully supported.
1.0 should possibly be used for RAID1 arrays that you
want to boot off, depending on your boot loader.
