There are probably more Linux devices using SCSI than NVMe. There are
several billion Android phones in use. Modern Android phones use UFS
storage. UFS is based on SCSI. There are already UFS devices available
that support more than 300K IOPS and there are plans for improving
performance further. Moving the SCSI stack to user space would have a
very significant negative performance impact on Android devices.
