The HW fence ctx objects are not ref counted rather tied to the life of
an LRC object. HW fences reference the HW fence ctx, HW fences can
outlive LRCs thus resulting in UAF. Drop the HW fence pointer to HW
fence ctx rather just store what is needed directly in HW fence.

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.
