The links work if you are browsing the document via GitHub: https://github.com/torvalds/linux/blob/master/Documentation/bpf/bpf_devel_QA.rst But I'm fine with removing those links as the official doc is here: https://www.kernel.org/doc/html/latest/bpf/bpf_devel_QA.html > As Alexei Starovoitov suggested, just remove "MAINTAINERS" and > "samples/bpf/" links and use correct link of "selftests". > > [1] https://www.kernel.org/doc/html/MAINTAINERS > [2] https://www.kernel.org/doc/html/samples/bpf/ > [3] https://www.kernel.org/doc/html/tools/testing/selftests/bpf/ > [4] https://www.kernel.org/doc/html/latest/bpf/bpf_devel_QA.html > > Fixes: 542228384888 ("bpf, doc: convert bpf_devel_QA.rst to use RST formatting") > Signed-off-by: Tiezhu Yang <yangtiezhu@xxxxxxxxxxx> > --- > > v3: Remove "MAINTAINERS" and "samples/bpf/" links and > use correct link of "selftests" > > v2: Add Fixes: tag > > Documentation/bpf/bpf_devel_QA.rst | 17 ++++++++--------- > 1 file changed, 8 insertions(+), 9 deletions(-) > > diff --git a/Documentation/bpf/bpf_devel_QA.rst b/Documentation/bpf/bpf_devel_QA.rst > index 2ed89ab..d05e67e 100644 > --- a/Documentation/bpf/bpf_devel_QA.rst > +++ b/Documentation/bpf/bpf_devel_QA.rst > @@ -29,7 +29,7 @@ list: > This may also include issues related to XDP, BPF tracing, etc. > > Given netdev has a high volume of traffic, please also add the BPF > -maintainers to Cc (from kernel MAINTAINERS_ file): > +maintainers to Cc (from kernel ``MAINTAINERS`` file): > > * Alexei Starovoitov <ast@xxxxxxxxxx> > * Daniel Borkmann <daniel@xxxxxxxxxxxxx> > @@ -234,11 +234,11 @@ be subject to change. > > Q: samples/bpf preference vs selftests? > --------------------------------------- > -Q: When should I add code to `samples/bpf/`_ and when to BPF kernel > -selftests_ ? > +Q: When should I add code to ``samples/bpf/`` and when to BPF kernel > +selftests_? > > A: In general, we prefer additions to BPF kernel selftests_ rather than > -`samples/bpf/`_.
