If you are worried about size, disable tracing and it will go away entirely. 0.5KiB is a drop in the bucket compared to what tracing adds in size overhead. Sorry, but NAK. This has been very successful in stopping people from adding trace_printk() to the kernel, and I like to keep it that way. -- Steve
