Given that this only matters for cgroup writeback cases, this should
still be fairly low impact, so I don't think it'd matter too much
whether we fix this in this cycle or for 4.6. However, that also means
that we're not risking much by doing it in this cycle, so I'd vote for
doing it now.

Thanks.
