With the introduction of zoned block device support in the kernel, accessing discovering if a block device is zoned and accessing its zone layout information does not require using SG_IO anymore. The file /sys/block/<dev>/queue/zoned indicates the device zone model and the ioctls BLKREPORTZONE and BLKRESETZONE defined in include/uapi/linux/blkzoned.h allow manipulating zones more easily.
This patch series brings in support for this new interface in place of the direct SG_IO-zbc commands. In addition, it enforces some formtating options for host-managed zoned block devices and straighten device zone layout checks to make sure that the device can be used. Finally, as discard does not result in write pointer zone reset, the ioctl BLKRESETZONE is used during formatting to properly initialize all sequential zones of the device.
