[Qemu-block] [PATCH v3 7/7] iotests: Set read-zeroes on in null block driver for Valgrind |
|
Date: |
Fri, 28 Jun 2019 16:46:14 +0300 |
The Valgrind tool reports about the uninitialised buffer 'buf'
instantiated on the stack of the function guess_disk_lchs().
It is revealed in the tests 051, 186, 227 and 240.
Pass 'read-zeroes=on' to the null block driver in the mentioned tests
to make them deterministic.
The output of the tests above now includes the parameter 'read-zeroes'.
So, the benchmark output files are being changed too.
