Regarding this, has anyone been thinking of splitting printk into a bunch of macros such as:
#ifndef CONFIG_TINY #define printk_debug(xxx...) printk(KERN_DEBUG, xxx...) #define printk_info(xxx...) printk(KERN_INFO, xx...) #else #define printk_debug(xxx...) do { } while (0) #define printk_info(xxx...) do { } while (0) #endif
and so on? This way debug messages could very simply be compiled to oblivion when CONFIG_TINY is enabled.
