Hi John,

The first patch in this series fix a bad character used instead of a "(c)" UTF-8 symbol.

The remaining ones fix several broken references to files under Documentation/, several due to DT schema conversions from .txt to .yaml.

No I don't believe it should. BPFTOOL_DIR already contains 'tools/bpf/bpftool' and the os.path.join() concatenates the two path fragments.

Where is this suggestion coming from? Did you face an issue with the script?

Same comment applies for the next two patches.

No, I didn't face any issues with this script.

The suggestion cames from the script at:

./scripts/documentation-file-ref-check

which is meant to discover broken doc references.

Such script has already a rule to handle stuff under tools/:

# Accept relative Documentation patches for tools/ if ($f =~ m/tools/) { my $path = $f; $path =~ s,(.*)/.*,$1,; next if (grep -e, glob("$path/$ref $path/../$ref $path/$fulref")); }

but it seems it needs a fixup in order for it to stop reporting issues at test_bpftool_synctypes.py:

$ ./scripts/documentation-file-ref-check ... tools/testing/selftests/bpf/test_bpftool_synctypes.py: Documentation/bpftool-prog.rst tools/testing/selftests/bpf/test_bpftool_synctypes.py: Documentation/bpftool-map.rst tools/testing/selftests/bpf/test_bpftool_synctypes.py: Documentation/bpftool-cgroup.rst

I'll drop the patches touching it for a next version, probably adding a fix for such script.

Thanks, Mauro

[PATCH] scripts: documentation-file-ref-check: fix bpf selftests path

tools/testing/selftests/bpf/test_bpftool_synctypes.py use relative patches on the top of BPFTOOL_DIR:

BPFTOOL_DIR = os.path.join(LINUX_ROOT, 'tools/bpf/bpftool')

Change the script to automatically convert:

testing/selftests/bpf -> bpf/bpftool

In order to properly check the files used by such script.

}

I tested the patch and it works well on my side.

However, this looks a bit fragile to me. There is no particular reason to have testing/selftests/bpf point to bpf/bpftool other than to accommodate the current case, we could imagine other selftest files pointing to other parts of the documentation in the future. I would instead make an exception for test_bpftool_synctypes.py specifically (other selftest files don't usually parse documentation anyway). Alternatively, I would look at excluding lines where the path is used in code (tricky to detect), maybe at least when used with os.path.join():

next if ($ln =~ m,os.path.join([^,]*,\s*['"]$fulref,);

But I'm not familiar with documentation-file-ref-check in the first place, so these are just my two cents.
