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?
