Jiri Olsa says: ==================== hi, I noticed several times in discussions that we should move test kfuncs into kernel module, now perhaps even more pressing with all the kfunc effort. This patchset moves all the test kfuncs into bpf_testmod. I added bpf_testmod/bpf_testmod_kfunc.h header that is shared between bpf_testmod kernel module and BPF programs. v4 changes: - s390 supports long calls [1] now, so it can call now kfuncs from module [Ilya] - added acks [David] - cleanups for ptr_to_u64 function [David] - use relative path for bpf_testmod_kfunc.h include [Andrii] - new libbpf fix (patch 1) for gen_loader v3 changes: - added acks [David] - added bpf_testmod.ko make dependency for bpf test progs [David] - better handling of __ksym and refcount_t in bpf_testmod_kfunc.h [David] - removed 'extern' from kfuncs declarations [David] - typo in header guard macro [David] - use only stdout in un/load_bpf_testmod v2 changes: - add74bc3a5accinto bpf-next/master CI, so the test would pass https://github.com/kernel-patches/vmtest/pull/192 - remove extra externs [Artem] - using un/load_bpf_testmod in other tests - rebased thanks, jirka [1]1cf3bfc60fbpf: Support 64-bit pointers to kfuncs ==================== 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.
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.
