zloop_rw() will fail any regular write operation that targets a full
sequential zone. The check for this is indirect and achieved by checking
the write pointer alignment of the write operation. But this check is
ineffective for zone append operations since these are alwasy
automatically directed at a zone write pointer.
Prevent zone append operations from being executed in a full zone with
an explicit check of the zone condition.

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.
