When running on a ramdisk, the fsstress background workload consumes a GB of disk space every 5 seconds. This leads to the test failing with ENOSPC because the test file cannot be created due otthe background load cosuming it all. Hence don't run this test unless the scratch device is large enough not to hit ENOSPC conditions.
