We can still put it into Disco (19.04)'s kernel (v5.0) and see how it goes.
If no regression happens for a while, we can back port it to v4.15.

I'd like to wait till they at least land to v5.1-rc and get more thoroughly

I'll request an SRU once they are there.

I've tested this kernel - there's no latency spike when setting none

Seems to be not that trivial without commit
