====================
Fix yet another case of mishandling SEC("struct_ops") programs that were
nulled out programmatically through BPF skeleton by the user.
While at it, add some improvements around detecting and reporting errors,
specifically a common case of declaring SEC("struct_ops") program, but
forgetting to actually make use of it by setting it as a callback
implementation in SEC(".struct_ops") variable (i.e., map) declaration.
A bunch of new selftests are added as well.

============
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 reStructuredText 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.
