But are there any numbers how much separate sprintf.h might safe? Maybe, we should not reinvent the wheel and get inspired by userspace. sprintf() and friends are basic functions which most people know from userspace. And it is pretty handy that the kernel variants are are mostly compatible as well. IMHO, it might be handful when they are also included similar way as in userspace. From my POV printk.h is like stdio.h. And we already have include/linux/stdarg.h where the v*print*() function might fit nicely. How does this sound, please? Best Regards, Petr
