That doesn't look related - the device claims to not support flush or fua, and the bug resulted in us not sending flush/fua devices; the main thing people would see without that patch, on 6.8, would be an immediate -EOPNOTSUP on the first flush journal write. He only got errors after an hour or so, or 10 minutes with UAS disabled; we send flushes once a second. Sounds like a screwy device.
