*	qed: Add support for zero clusters	Anthony Liguori	2011-04-13	1	-10/+21
\| \| \| \| \| \| \| \| \| \| \| \| \|	Zero clusters are similar to unallocated clusters except instead of reading their value from a backing file when one is available, the cluster is always read as zero. This implements read support only. At this stage, QED will never write a zero cluster.

*	qed: Table, L2 cache, and cluster functions	Stefan Hajnoczi	2010-12-17	1	-0/+154
	This patch adds code to look up data cluster offsets in the image via the L1/L2 tables. The L2 tables are writethrough cached in memory for performance (each read/write requires a lookup so it is essential to cache the tables). With cluster lookup code in place it is possible to implement bdrv_is_allocated() to query the number of contiguous allocated/unallocated clusters.
