Yes, this is indeed the concern. So, the idea I had was to invoke quiet_vmstat() regardless if the tick was stopped or not. If I understand correctly, this should resolve the issue. Furthermore, folding of all outstanding differentials will only occur when required. Thus performance should be negligible.
