Does this mean that this patch series doesn't fix reordering caused by
recursive splitting for zoned block devices? A test case that triggers
an I/O error is available here:
https://lore.kernel.org/linux-block/a8a714c7-de3d-4cc9-8c23-38b8dc06f5bb@acm.org/

I have not yet had the time to review this patch series but plan to take
a look soon.

Thanks,

Bart.
