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

Debugging by printing

printk(KERN_ERR "Doing something was ");
/* <100 lines of whatever>*/
if (success)
   printk(KERN_CONT "successful\n");
else
   printk(KERN_CONT "NOT successful\n");

Logging prints should be safe: SFP vs single CPU.
