Pre/post (un)patch callbacks might manipulate the system state. Cumulative livepatches might need to take over the changes made by the replaced ones. For this they might need to access some data stored or referenced by the old livepatches. Therefore the replaced livepatches have to stay around until post_patch() callback is called. It is achieved by calling the free functions later. It is the same location where disabled livepatches have already been freed.

README
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.
