Except for tracing, the pointer is not used. At the same time, accessing it from qeth_qdio_output_handler() is racy: whenever qeth_qdio_cq_handler() gets control, its call to qeth_qdio_handle_aob() frees the AOB. So the AOB pointer that qeth_qdio_output_handler() stores into 'buffer' can go stale at any time, and trigger a use-after-free.

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
