I assume that above refers to this kernel patch series.

  https://lore.kernel.org/linux-nvme/20260812181300.3712426-1-jtaubepe@redhat.com/

I applied the series on top of v7.2-rc7 kernel. Then I ran the test case added
by this blktests series and observed the failurea below:

Is this failure expected?

I will comment on each patch in line.
