It also depreciates the unit of the new userspace tunable. > but today i catch log from my desktop. oom-killer have kill my "minicom" and > "Xorg". so i think it should add protection about it. > Because Xorg was killed does necessarily mean we need to add more heursitics to the oom killer. In fact, if you are to again suggest the 3% memory bonus for these tasks, you should be able to show that the same result cannot happen even with your patch. I don't believe you've made a case for that and making all CAP_SYS_RAWIO tasks immune from oom killing as a default choice would be inappropriate. If the kernel is killing Xorg, that means it is the most memory-hogging task on the system and it is following the heuristic's core principle: kill the most memory-hogging task to free a large amount of memory to prevent additional oom kills in the near future if allowed by userspace. The kernel doesn't realize that Xorg is important to you and me, it needs to tell it using /proc/pid/oom_score_adj. Throwing additional heuristics for things like CAP_SYS_RAWIO is short-sighted, however, because the capability itself doesn't have any direct correlation to a memory quantity or oom killing preference.

showing the "Killed process ... total-vm:...kB, anon-rss:...kB, file--rss:...kB" line that indicates anything was killed. In fact, your entire log doesn't show that. minicom simply invoking the oom killer (and Xorg later) doesn't indicate a problem. Please post a complete log that shows the tasklist dump and which task was selected from that state. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
