====================
This patch set adds unified OPTS-based low-level bpf_prog_load() API for
loading BPF programs directly into kernel without utilizing libbpf's
bpf_object abstractions. This OPTS-based interface allows for future
extensions without breaking backwards or forward API and ABI compatibility.
Similar approach will be used for other low-level APIs that require extensive
sets of parameters, like BPF_MAP_CREATE command.
First half of the patch set adds libbpf API, cleans up internal usage of
to-be-deprecated APIs, etc. Second half cleans up and converts selftests away
from using deprecated APIs. See individual patches for more details.
v1->v2:
- dropped exposing sys_bpf() into public API (Alexei, Daniel);
- also dropped bpftool/cgroup.c fix for unistd.h include because it's not
necessary due to sys_bpf() staying as is.

============
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.
