io_uring cause data corruption
...uring module.
Before I spend more time on this I'd like you to
create a standard ext4 filesystem, create all the
files with cp *without* using reflink (which ext4
doesn't support) so we know there's no COW shenanigans
and then copy from *that* filesystem to the Windows client
using the iouring module.
I'm not a betting man, but if I was I'd bet the problem
dissapears :-).

Well, the issue is that e.g., iouring fixed buffers can be accessed from
the CPU using the direct map from the CPU, not necessarily using DMA
from a device.
In any case, I'm planning on adding some code-level documentation for
that and look into extending the high-level doc while at it.

So, I found a 160GB USB disk that I formatted to ext4 and exported it as:
