Yu Li e98ea329bf block: qcow: read from the backing file if present on read miss ... Reads to qcow files with backing files will fall through to the backing file if there is no allocated cluster. As of this change, a write will still trash the cluster and hide any data already present. This commit is based on crosvm implementation: https://chromium.googlesource.com/crosvm/crosvm/+/d8144a56e26ca09e2c7ff97ed63c57e7e7965674 Signed-off-by: Yu Li <liyu.yukiteru@bytedance.com>		2023-07-19 13:52:43 +01:00
