Dear Documentation Project team,

The advisory link used for linux_futex in errata notes:
https://www.freebsd.org/security/advisories/FreeBSD-EN-21:22.linux_futexasc
is missing a period at the end. It should be:
https://www.freebsd.org/security/advisories/FreeBSD-EN-21:22.linux_futex.asc

Impacted pages include at least:
https://www.freebsd.org/releases/11.4R/errata/
https://www.freebsd.org/releases/12.2R/errata/
https://www.freebsd.org/releases/13.0R/errata/
but not
https://www.freebsd.org/security/notices/

Best regards,
