Hmm, right. Well that Python script basically just parses
include/uapi/linux/bpf.h; and it can be given the path of that file with
the --filename argument. So as long as that file is present, it should
be possible to make it work, I guess?
However, isn't the point of the tarball to make a "stand-alone" source
distribution? I'd argue that it makes more sense to just include the
generated header, then: The point of the Python script is specifically
to extract the latest version of the helper definitions from the kernel
source tree. And if you're "freezing" a version into a tarball, doesn't
it make more sense to also freeze the list of BPF helpers?
