Yes, thats exactly the problem.
So for example if we'd switch to allocating the jumpstack in the percpu
area (rather than just a pointer as we do now) we would need to revert
that since percpu allocations have sie limitations (64k max iirc).

HOWEVER, the real problem is -- if you apply this, how long would
you propose to wait before we would leverage the limitation in further
patches?

I'd say 3 years minimum, and I'd rather see nft ready by then :)

So I'd say drop patch 6.
