I once dealt with WARN_CONSOLE_UNLOCKED(), and back then, IIRC, I really wanted to turn it into WARN_ONCE_CONSOLE_UNLOCKED(), which would WARN_ON_ONCE() instead of WARN_ON(). It's just a bit too noisy and verbose and a single backtrace was already enough. -ss -- To unsubscribe from this list: send the line "unsubscribe linux-fbdev" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
