From: Zhang Yi <yi.zhang@xxxxxxxxxx>
Test block device unmap write zeroes sysfs interface with NVMeT devices
which are based on various SCSI debug devices. The
/sys/block/<disk>/queue/write_zeroes_unmap interface should return 1 if
the NVMeT devices support the unmap write zeroes command, and it should
return 0 otherwise.
