Benjamin Tissoires 979497674e bpf: Allow kfunc in tracing and syscall programs.
Tracing and syscall BPF program types are very convenient to add BPF
capabilities to subsystem otherwise not BPF capable.
When we add kfuncs capabilities to those program types, we can add
BPF features to subsystems without having to touch BPF core.

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.
