(/proc/[pid]/numa_maps is very slow, we can't use it at memory shortage emergency) I think we need develop per zone rss. it become not only improve mem_notify, but also improve oom killer of more intelligent process choice. but it is a bit difficult. (at least for me ;-) may be, I will implement it a bit later... Thanks again! your good opnion may improve my patch. - kosaki - To unsubscribe from this list: send the line "unsubscribe linux-fsdevel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
