The linux-5.4.y commit8781011a30("bpf: Test_progs, add test to catch retval refine error handling") fails to build when libbpf headers are not installed, as it tries to include <bpf/bpf_helpers.h>: progs/test_get_stack_rawtp_err.c:4:10: fatal error: 'bpf/bpf_helpers.h' file not found For 5.4-stable (only) the new test prog needs to include "bpf_helpers.h" instead (like all the rest of progs/*.c do) because 5.4-stable does not carry commite01a75c159("libbpf: Move bpf_{helpers, helper_defs, endian, tracing}.h into libbpf").

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.
