Yes, please test it, you can ignore may previous comments as they are irrelevant now.
Here is the link to the mentioned patch:
https://lore.kernel.org/dm-devel/03e58462-5045-e12f-9af6-be2aaf19f32c@redhat.com/T/#u
I think that the issue is clear (as found by Mikulas)
- DM device (dm-integrity here) does not receive the FLUSH command here.
This would explain all issues you see. If the patch works, it should be fixed in stable kernels
as it impacts other more complex storage configurations.
Thanks,
Milan
