Thanks for answers.

But I was referring to "printks" that are in functions of my module no "printfs". I mean in my user code I make a call of function fwrite before calling function ioctl and in the terminal I saw "printks" of ioctl before printks of fwrite and all "printks" that I have written in the module have the same priority. And also why "printks" of ioctl can appear in terminal if I don't make a call of function "ioctl", I have chosen a unique magic number.

Thanks in advice
