This is still very fuzzy. What are you actually trying to achieve?I don't expect page fault any more after mlock.
This should be the case normally. Except when mm_populate fails which can happen e.g. when running inside a memcg with the hard limit configured. Is there any other unexpected failure scenario you are seeing? -- Michal Hocko SUSE Labs -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.
