hm, drat, I was suspecting dependency issues here, but a test build said it was OK.
Actually, I was expecting this patch series to depend on the linux-next cgroup2 changes, but that doesn't appear to be the case. *should* this series be staged after the cgroup2 code?
Regarding this particular series: yes, I think we can live with a bisection hole for !CONFIG_INET && CONFIG_MEMCG users. But I'm not sure why we're discussing bisection issues, because Arnd's build failure occurs with everything applied?

This sort of thing happens quite rarely.
