/dev/urandom is incompressible and, /dev/zero is highly compressible, so both are less effective in testing the compress code logic in btrfs. This patch introduces a text data generator cat /dev/urandom | od to populate the files where /dev/urandom is currently being used in the btrfs test cases. And updates the _populate_fs() with a new option -c, so to instruct to use the compressible data to populate the file(s).
