Hmmm? I meant the eventual calling into try_charge w/ GFP_NOWAIT. Speculative usage of GFP_NOWAIT is bound to increase and we don't want to put on extra restrictions from memcg side. For memory.high, punting to the return path is a pretty stright-forward solution which should make the problem go away almost entirely.
