There exist some errors "404 Not Found" when I click the link
of "MAINTAINERS" [1], "samples/bpf/" [2] and "selftests" [3]
in the documentation "HOWTO interact with BPF subsystem" [4].

As Jesper Dangaard Brouer said, the links work if you are browsing
the document via GitHub [5], so I think maybe it is better to use
the corresponding GitHub links to fix the issues in the kernel.org
official document [4], this change has no influence on GitHub and
looks like more clear.

The initial aim is to fix the invalid links, sorry for the noisy.

v4: Use the corresponding GitHub links

v3: Remove "MAINTAINERS" and "samples/bpf/" links and
    use correct link of "selftests"

v2: Add Fixes: tag
