ZBC drives are close to disk devices, so sd.c is well
suited as a testbed for ZBC devices.
This patch introduces a module option 'attach_zbc' to
sd which will make the sd driver accept ZBC
devices as normal disk drives.

Looks reasonable to me.
I'd also really like a sysfs file that tells us if we're dealing
with a host aware device, as those report as TYPE_SBC.
Yes, eventually. But can't we defer that to a next patchset?
I'd really like to have this one in, as it makes dealing with ZAC
devices _so much_ easier ...
Cheers,
Hannes
