During stress testing we want to cover as much code paths as possible fsstress is very good for this purpose. But it has expandable nature (disk usage almost continually grow). So once it goes in no ENOSPC condition it will be where till the end. But by running 'dd' writers in parallel we can regularly trigger ENOSPC but only for a limited periods of time because each time it opens the same file with O_TRUNC.
