No zone plugs are allocated when a zone is opened by calling Zone Append
on it. This makes the cached zone reporting report incorrectly empty
zones if the file system is unmounted and report zones is called after
that, e.g. by xfstests test cases using the scratch device.
Fix this by recording if zone append was used on a device, and disable
cached reporting for the device until a ZONE_RESET_ALL happens that
guarantees all zones are empty.
We could probably do even better using a per-zone flag, but the practical
use cache for zone reporting after the initial mount are rather limited,
so let's keep things simple for now.

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 reStructuredText 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.
