For plain text output, it incorrectly prints the pointer value
"void *data". The "void *data" is actually pointing to memory that
contains a bpf-map's value. The intention is to print the content of
the bpf-map's value instead of printing the pointer pointing to the
bpf-map's value.
In this case, a member of the bpf-map's value is a pointer type.
Thus, it should print the "*(void **)data".

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.
