Andrii Nakryiko says: ==================== This patch set adds ability to auto-generate list of BPF helper definitions. It relies on existing scripts/bpf_helpers_doc.py and include/uapi/linux/bpf.h having a well-defined set of comments. bpf_helper_defs.h contains all BPF helper signatures which stay in sync with latest bpf.h UAPI. This auto-generated header is included from bpf_helpers.h, while all previously hand-written BPF helper definitions are simultaneously removed in patch #3. The end result is less manually maintained and redundant boilerplate code, while also more consistent and well-documented set of BPF helpers. Generated helper definitions are completely independent from a specific bpf.h on a target system, because it doesn't use BPF_FUNC_xxx enums. v3->v4: - instead of libbpf's Makefile, integrate with selftest/bpf's Makefile (Alexei); v2->v3: - delete bpf_helper_defs.h properly (Alexei); v1->v2: - add bpf_helper_defs.h to .gitignore and `make clean` (Alexei). ==================== 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.
