From: Zhang Yi <yi.zhang@xxxxxxxxxx>
The Linux kernel is planning to support FALLOC_FL_WRITE_ZEROES in
fallocate(2). Add tests for the newly added BLK_FEAT_WRITE_ZEROES_UNMAP
feature flag on the block device queue limit. These tests test block
device unmap write zeroes sysfs interface
/sys/block/<disk>/queue/write_zeroes_unmap
with various SCSI/NVMe/device-mapper devices.
The /sys/block/<disk>/queue/write_zeroes_unmap interface should return
1 if the block device supports unmap write zeroes command, and it should
return 0 otherwise.
- scsi/010 test SCSI devices.
- dm/003 test device mapper stacked devices.
- nvme/060 test NVMe devices.
Thanks,
Yi.
