Build the kernel and selftest with clang compiler with LLVM=1,
make -j LLVM=1
make -C tools/testing/selftests/bpf -j LLVM=1
I hit the following selftests/bpf compilation error:
In file included from test_cpp.cpp:3:
/.../tools/testing/selftests/bpf/tools/include/bpf/libbpf.h:73:8:

There are two ways to fix the issue, one is to use GCC diagnostic ignore pragma, and the
other is to open code bpf_object_open_opts instead of using LIBBPF_OPTS.
Since in general LIBBPF_OPTS is preferred, the patch fixed the issue by
adding proper GCC diagnostic ignore pragmas.

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.
