Can you expand on _why_ -EOPNOTSUPP handling is no longer needed? And
please at it to the final patch header.
This removal isnt unique to DMs conversion to FLUSH+FUA but I couldnt
easily find the justification for its removal in the larger 30+ patch
patchset either -- other patches are terse on the removal too.
Other than that.
