Ah, because I hadn't added dm-logwrite support to check-parallel
this test wasn't being run....

However, this patch doesn't need to exist - this dependency is
removed  later in the series by using the changes to use a unique
session ID for each test and so the fsstress binary doesn't need to
be rename. The change in this patch is then reverted....

I'd just drop this patch (and the later revert).
