The ZNS specification introduces the concept of a Zone Capacity. A zone capacity is an additional per-zone attribute that indicates the number of usable logical blocks within each zone, starting from the first logical block of each zone. It is always smaller or equal to the zone size. With the SINGLE profile, we can set a block group's "capacity" as the same as the underlying zone's Zone Capacity. We will limit the allocation not to exceed in a following commit.

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.
