[PATCH v2 18/21] iotests: Make 137 work with data_file |
Date: |

When using an external data file, there are no refcounts for data
clusters. We thus have to adjust the corruption test in this patch to
not be based around a data cluster allocation, but the L2 table
allocation (L2 tables are still refcounted with external data files).
Furthermore, we should not print qcow2.py's list of incompatible
features because it differs depending on whether there is an external
data file or not.
With those two changes, the test will work both with an external data
files (once that options works with the iotests at all).
