While commitcf28f6f923("zloop: fail zone append operations that are targeting full zones") added a check in zloop_rw() that a zone append is not issued to a full zone, commite3a96ca904("zloop: simplify checks for writes to sequential zones") inadvertently removed the check to verify that there is enough unwritten space in a zone for an incoming zone append opration. Re-add this check in zloop_rw() to make sure we do not write beyond the end of a zone. Of note is that this same check is already present in the function zloop_set_zone_append_sector() when ordered zone append is in use.

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.
