Subject: Question about seccomp / bpf

Hi Alexei and Daniel

I have a question about seccomp.

It seems that after this patch, seccomp no longer needs a helper

Are we detecting that a particular JIT code needs to call at least one
function from the kernel at all ?

If the filter contains self-contained code (no call, just inline
code), then we could use any room in whole vmalloc space,
not only from the modules (which is something like 2GB total on x86_64)
