Hello Jens,
SMR support for fio has been reworked. The reworked patches are available at
https://github.com/axboe/fio/pull/585. The following two test scripts allow to
verify whether the fio behavior is identical for SMR and non-SMR storage media:
* t/zbd/run-tests-against-regular-nullb
* t/zbd/run-tests-against-zoned-nullb
Thanks,
Bart.
