Yes, I have seen oflags=sync

However, it seems like a big waste to handle the whole x GiB synchronously, just to know when the last block has been written.

I have not measured though. And I have not tested whether it solves the /dev/sdX -- /dev/sdX1 coherence issue.

For the more common case of USB removal (not my problem here) I have found

udiskctl power-off

in the meantime. At least for everybody using systemd.
