[svn-r5113] Purpose:
feature Description: Added -fsize <fsize> option which controls the family file size used. This can be used to test the file size limits of a machine or file system. Platforms tested: modi4 (passed even 20GB file size). Eirene (started to fail when 2GB is used. Expected since linux 2.2 does not support large than 2GB file size.) burrwhite (passed up to 4GB. Expected since Linux 2.4 supports larger than 2GB file size.) Then it failed at 4GB and beyond. This is probably a bug in the family file driver.
