commit 02df38e93e25e07f4d54edae94fb4ec90b7a2824

Author: Santhosh G <santhog4@linux.vnet.ibm.com>

    Defined task size value to be 512T if it is more that 64Tb.

    The Test case needs to loop till 512Tb to get the TASK_SIZE value.

    This patch defines the value to be 512T if the test tries to loop

    above 64T.
