A target driver support zoned block devices and exposing it as such may receive REQ_OP_ZONE_REPORT request for the user to determine the mapped device zone configuration. To process properly such request, the target driver may need to remap the zone descriptors provided in the report reply. The helper function dm_remap_zone_report() does this generically using only the target start offset and length and the start offset within the target device. dm_remap_zone_report() will remap the start sector of all zones reported. If the report includes sequential zones, the write pointer position of these zones will also be remapped.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
