We don't check version numbers in fstests, but actually try what is requested and _notrun if the test run failed. I think we can keep _require_dm_target unchanged and add a new _require_dmflakey_error_writes in common/dmflakey, e.g. _require_dmflakey_error_writes() { _require_dm_targets flakey <try creating flakey table with error_writes option here and _notrun if failed> } And call this new _require rule in the test.
