Failures seem related:

Syscall filter could not be installederrorfailed to assemble policy: found unknown syscalls for arch x86_64: clone3

Could it be because of the base images used? @simitt is this change needed in 7.16 and 7.15?

[andrewkroh]

I think #27955 needs backported in order to update go-seccomp-bpf with new syscall tables that include clone3.

[simitt]

@jsoriano somehow I missed your ping; if anyhow possible this should go into 7.16, seems we missed 7.15.2 unfortunately.
