Tasks are moved directly on behalf of a request from userspace. We would much prefer denying that single request than invoking the oom-killer on the whole group. Quite a lot changed in the trycharge-reclaim-retry path since 2009. Nowadays, charging is retried as long as reclaim is making any progress at all, so I don't see that it would give up moving a task too lightly, even without the extra OOM looping. Is there any chance you could retry with a more recent kernel? -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@xxxxxxxxx.
