The Adaptec out-of-tree driver did this correctly. After comparing the two

With module parameter virtual_gb 0, the device accesses may go beyond
the actual ramdisk storage (fake_storep). Such requests should be
treated as fake_storep is repeatedly mirrored up to virtual size
(virtual_gb * 1GB).
Unfortunately, WRITE_SAME commands with such requests access out of
This patch set includes bug fixes with certain module parameters of
scsi_debug. First one fixes bug with num_parts 0. Others fix logical
block provisioning support with unmap_alignment != 0 and with virtual_gb 0.
Akinobu Mita (4):
scsi_debug: fix endianness bug in sdebug_build_parts()
With module parameter num_parts 0, partition table is built on the
ramdisk storage when loading the driver. Unfortunately, there is an
endianness bug in sdebug_build_parts(). So the partition table is not
correctly initialized on big-endian systems.

With logical block provisioning support enabled, the provisioning map
(map_storep) keeps track of the provisioning status (mapped or unmapped)
for actual ramdisk storage range (fake_storep). The provisioning status
for out of fake_storep range with module parameter virtual_gb 0 is
not tracked,
Commit b90ebc3d5c41c9164ae04efd2e4f8204c2a186f1 ([SCSI] scsi_debug:
fix logical block provisioning support) fixed several issues with
logical block provisioning support, but it still doesn't properly fix
the cases when unmap_alignment 0. (for example, unmap_alignment=1
and unmap_granularity=3)
