This allows overriding the global sysctl value with a per-socket one.

It seems EXPORT_SYMBOL_GPL(sysctl_net_ll_poll) can now be removed ?

I think we would need it for poll.

Poll needs a way that is not dependent on any individual socket to know
how long to busy-wait, since we have to know it before we poll any
individual socket.

The patch I have right now for poll is not ready (and not fully tested).
But I can post it as an RFC if you want.
