Hmm, I'm not sure we should allow clone3 unconditionally since it can do lots of things, and I'd expect that its capabilities will only grow over time. OTOH, BPF (or at least the libseccomp library) don't support pointer indirections which would be needed to inspect the structure fields. See https://lwn.net/Articles/822256/.
Any opinions?
