ZBC-2 allows host-managed disks to report gap zones. This allow zoned disks to report an offset between data zone starts that is a power of two even if the number of logical blocks with data per zone is not a power of two. Another new feature in ZBC-2 is support for constant zone starting LBA offsets. For zoned disks that report a constant zone starting LBA offset, hide the gap zones from the block layer. Report the offset between data zone starts as zone size and report the number of logical blocks with data per zone as the zone capacity.

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.
