It happens when CONFIG_PROC_FS is not enabled (or is it CONFIG_SYSFS?). I reported it for linux-next of 20110526: when CONFIG_PROC_FS is not enabled: drivers/built-in.o: In function `node_read_vmstat': node.c:(.text+0x56ffa): undefined reference to `vmstat_text' --- ~Randy *** Remember to use Documentation/SubmitChecklist when testing your code *** -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@xxxxxxxxx.
