Add zoned storage support to ublk: report_zones and operations: - REQ_OP_ZONE_OPEN - REQ_OP_ZONE_CLOSE - REQ_OP_ZONE_FINISH - REQ_OP_ZONE_RESET - REQ_OP_ZONE_APPEND The zone append feature uses the `addr` field of `struct ublksrv_io_cmd` to communicate ALBA back to the kernel. Therefore ublk must be used with the user copy feature (UBLK_F_USER_COPY) for zoned storage support to be available. Without this feature, ublk will not allow zoned storage support.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
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.
