The Valgrind tool reports about the uninitialised buffer 'buf' instantiated on the stack of the function guess_disk_lchs(). Pass 'read-zeroes=on' to the null block driver to make it deterministic. The output of the tests 051, 186 and 227 now includes the parameter 'read-zeroes'. So, the benchmark output files are being changed too.
