I do not observe any ill effects, possibly because I do not really use raid. The command in question seems to be RAID_VERSION. I have verified that reverting aa98aa31987ad9831711ae71ea2270228ab62532 makes the errors go away. Didn't yet bother opening a bugzilla for this, let me know if I should. -- MST -- 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/
