While the other patches all look fine with me I strongly disagree with
this one.  Devices reporting the ZBC device type must have sequential
required zones, so they are _not_ anywhere close to disk devices,
and writes to them will cause errors that we aren't evenable able to
handle yet.

If it makes some sort of experiment easier for you we can add a way to
force ZBC devices to use sd.c conditionally.  Do you have a test device
that this works with?
