How to print a message in one single line in Linux kernel

Question

I am making a simple enque/deque program in kernel. I want to print message in kernel, and this is what I got:

[18594.595747] Enqueue 3 
[18594.595748]  queu         


        

Answer 1

To prevent a new line from being started, use KERN_CONT:

printk(KERN_ALERT "self destruction commences in ");
printk(KERN_CONT "%d", time_remaining);
printk(KERN_CONT " minutes\n");
