Re: [RFC] x86: restrict pid namespaces to 32 or 64 bit syscalls

> i386 vs x86-64 vs x32 is just one of many axes along which syscalls can be restricted (and for that matter, one axis if backward compatibility), and it does not make sense to burden the code with ad hoc filters. Designing a general filter facility which can be used to restrict any container to the subset of system calls it actually needs would make more sense, no?
I believe this is already in the newer versions of seccomp.
