There are some points in the reset process where if the code fails for some reason, and the system admin tries to initiate the reset process again we will get a kernel panic. This is because there aren't any protections in different fini functions that are called during the reset process. The protections that are added in this patch make sure that if the fini functions are called multiple times, without calling init functions between them, there won't be double release of already released resources.

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.
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.
