Jakub Kicinski says: ==================== Following patches address build issues after recent move to libbpf. For out-of-tree builds we would see the following error: gcc: error: samples/bpf/../../tools/lib/bpf/libbpf.a: No such file or directory libbpf build system is now always invoked explicitly rather than relying on building single objects most of the time. We need to resolve the friction between Kbuild and tools/ build system. Mini-library called libbpf.h in samples is renamed to bpf_insn.h, using linux/filter.h seems not completely trivial since some samples get upset when order on include search path in changed. We do have to rename libbpf.h, however, because otherwise it's hard to reliably get to libbpf's header in out-of-tree builds. v2: - fix the build error harder (patch 3); - add patch 5 (make clang less noisy). ==================== Signed-off-by: Alexei Starovoitov <ast@kernel.org>
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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
