Hi Huang, >+#ifdef CONFIG_NUMA_BALANCING >+ PGPROMOTE_SUCCESS, /* promote successfully */ I find a breakdown of Anon and File page promotion can often be useful to understand an application's behavior (i.e. what kind of pages are moved to remote node and later being promoted). What do you think about adding counters for such a breakdown? What's your thought on adding counters for failures on different reasons? Best, Hasan
