iotests/270: Don't store data-file with json: prefix in image
|
||
|
|
|
||
|
|
We want to disable filename parsing for data files because it's too easy
|
||
|
|
to abuse in malicious image files. Make the test ready for the change by
|
||
|
|
passing the data file explicitly in command line options.
