Daniel T. Lee 88795b4adb samples: bpf: Refactor BPF map in map test with libbpf From commit `646f02ffdd` ("libbpf: Add BTF-defined map-in-map support"), a way to define internal map in BTF-defined map has been added. Instead of using previous 'inner_map_idx' definition, the structure to be used for the inner map can be directly defined using array directive. __array(values, struct inner_map) This commit refactors map in map test program with libbpf by explicitly defining inner map with BTF-defined format.

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.
