Subject: mke2fs: enable bigalloc if -C is specified
From: Eric Sandeen <sandeen@redhat.com>
X-Patchwork-Id: 162194
Message-Id: <4FC7A1D5.3040805@redhat.com>
To: ext4 development <linux-ext4@vger.kernel.org>
Date: Thu, 31 May 2012 11:52:37 -0500

If -C is specified w/o -O bigalloc it has no effect and generates
no error.  If a cluster size is specified, that should imply
bigalloc.
