Extend the bpf hashmap docs to include a brief description of the internals of the LRU map type (setting appropriate API expectations), including the original commit message from Martin and a variant on the graph that I had presented during my Linux Plumbers Conference 2022 talk on "Pressure feedback for LRU map types"[0]. The node names in the dot file correspond roughly to the functions where the logic for those decisions or steps is defined, to help curious developers to cross-reference and update this logic if the details of the LRU implementation ever differ from this description.

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.
