From: Zhang Yi <yi.zhang@huawei.com> 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.
