v2 -> v3:

  * Patch 2: modify test case.  Increase number of requests from 1024 to
    2048; make odd requests write actual data, while even requests cause
    write_zeroes operation;

  * Add patch 3: add scripts/filev2p.py for mapping of virtual file
    offsets to physical block device offsets.  The script was used to
    initially track down the data corruption problem, so it's included
    here.
