add /dev/mem_notify device for notification low memory to user process. As you only wake one process how would you use this API from processes which want to monitor and can free memory under load. Also what fairness guarantees are there... Sorry, I don't make sense what you mean fairness. Could you tell more? If you have two processes each waiting on mem_notify is it not possible that one of them will keep being the one woken up and the other will remain stuck ? It also appears there is no way to wait for memory shortages (processes that can free memory easily) only for memory to start appearing. | ||||||||||
