Help text

This device-mapper target takes a host-managed or host-aware zoned block device and exposes most of its capacity as a regular block device (drive-managed zoned block device) without any write constraints. This is mainly intended for use with file systems that do not natively support zoned block devices but still want to benefit from the increased capacity offered by SMR disks. Other uses by applications using raw block devices (for example object stores) are also possible.

To compile this code as a module, choose M here: the module will be called dm-zoned.

If unsure, say N.
