Yes, just to be clear (and I'm pretty sure I'm agreeing with Greg here) any warnings that you want always enabled to show something in the kernel log whenever there's a problem should be dev_warn() or equivalent. Things that produce too much output and that you only want on when you're debugging a problem are probably best done via trace events. - R. -- Roland Dreier <rolandd@xxxxxxxxx> For corporate legal information go to: http://www.cisco.com/web/about/doing_business/legal/cri/index.html -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
