We plan to do an mlock() controller, so we will definitely gain from the noreclaim lists. The mlock() controller will put a limit on the amount of mlocked memory and reclaim in general will benefit from noreclaim lists, especially if the locked memory proportion is significant. -- Warm Regards, Balbir Singh Linux Technology Center IBM, ISTL -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.
