That's likely a missing kernel patch, as this is a regression test there
should have been links to the patches and CVE referencies in the test
output as the test is tagged with kernel commits and CVE numbers:

        .tags = (const struct tst_tag[]) {
                {"linux-git", "0fa3ecd87848"},
                {"CVE", "2018-13405"},
                {"CVE", "2021-4037"},
                {"linux-git", "01ea173e103e"},
                {"linux-git", "1639a49ccdce"},
                {"linux-git", "426b4ca2d6a5"},
                {}
        },

Possibly like the test may be missing check for a FAN_REPORT_DFID_FID
support.
