It looks like BLK_DEV_RBD needs to depend on INET and possibly on BLOCK (I sent a patch for depends on BLOCK on 2010-aug-04 due to other build errors). --- ~Randy *** Remember to use Documentation/SubmitChecklist when testing your code *** -- To unsubscribe from this list: send the line "unsubscribe linux-scsi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
