If you feel that this minor issue (which has never been reported in at least the last three years and doesn't have any side effects other than a couple of millisecond delay until unuse_mm() when the oom killer will kill something else) should be addressed in 2.6.35-rc2, then that's a conversation to be had with Andrew. -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.
