It's not abusing the system because it was killed, it was killed because it was abusing the system and attempted to mlock more memory than allowed in its exclusive mems. So we OOM the task but it can continue mlock'ing memory and intrude on the memory of other cpusets because of the TIF_MEMDIE exception and our SIGKILL hasn't been handled yet. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
