[Qemu-devel] [PATCH] qemu-iotests: New test case in 061 |
Date: |
Thu, 5 Sep 2013 10:55:54 +0200 |
Add one test case for zero cluster expansion on qcow2 version downgrade
in shared L2 tables (i.e., L2 tables with a refcount > 1) and one for
zero expansion on backed clusters in shared L2 tables.
Signed-off-by: Max Reitz <address@hidden>

Depends on (follow-up to):
- block/qcow2: Image file option amendment (series, v5)
