Subject: [Qemu-devel] [PATCH 1/8] vvfat: use bdrv_new() to allocate BlockDriverState
Date: Thu, 25 Jul 2013 17:01:39 +0800 [thread overview]
Message-ID: <1374742906-4489-2-git-send-email-famz@redhat.com> (raw)
In-Reply-To: <1374742906-4489-1-git-send-email-famz@redhat.com>
we need bdrv_new() to properly initialize BDS, don't allocate memory
manually.
