Great.

I'm aware of that and I'm planning to send a series of follow-up patches to
address the reverse translation issues, including Mac-specific paths and
partitions.

The translation code for NVME block devices (l2of_nvme and of2f_nvme) handles
partitions as well, so I think it makes sense to add that support for SCSI
devices, too, on all platforms.
I will try to send a patch series later this week to address these issues.
