Subject: [Qemu-devel] [PATCH v2 1/4] vmdk: fix L1 and L2 table size in vmdk3 open
Date: Tue, 13 Aug 2013 09:21:06 +0800	[thread overview]
Message-ID: <1376356869-19417-2-git-send-email-famz@redhat.com> (raw)
In-Reply-To: <1376356869-19417-1-git-send-email-famz@redhat.com>

VMDK3 header has the field l1dir_size, but vmdk_open_vmdk3 hardcoded the
value. This patch honors the header field.

And the L2 table size is 4096 according to VMDK spec[1], instead of
1 << 9 (512).
