Will it actually be necessary to change the kernel option name -- my impression was that the previous JIT (and possibly the new JIT) are actually entirely transparent to userspace applications -- they keep submitting BPF filters per normal...? In which case, perhaps there's no need to change the option name, as that would introduce an upgrade hurdle. Or is there sufficient difference that we want users to bump into it in order to understand that there has been an implementation change?
