The bpf-helpers(7) manual page shipped in the man-pages project is
generated from the documentation contained in the BPF UAPI header, in
the Linux repository, parsed by script/bpf_doc.py and then fed to
rst2man.
After a recent update of that page [0], Alejandro reported that the
linter used to validate the man pages complains about the generated
document [1]. The header for the page is supposed to contain some
attributes that we do not set correctly with the script. This commit
updates the "project and version" field. We discussed the format of
those fields in [1] and [2].
Before:
$ ./scripts/bpf_doc.py helpers | rst2man | grep '\.TH'
.TH BPF-HELPERS 7 "" "" ""
After:
$ ./scripts/bpf_doc.py helpers | rst2man | grep '\.TH'
.TH BPF-HELPERS 7 "" "Linux v5.19-14022-g30d2a4d74e11" ""
We get the version from "git describe", but if unavailable, we fall back
on "make kernelversion". If none works, for example because neither git
nore make are installed, we just set the field to "Linux" and keep
generating the page.

README
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.
