I use trace_printk() all the time for kernel, particularly RCU development.
One of the key usecases I have is dumping traces on panic (with panic on warn
and stop tracing on warn enabled). This is extremely useful since I can add
custom tracing and dump traces when rare conditions occur. I fixed several
bugs with this technique.

I also recommend keeping it convenient to use.

Okay, you know C, please share your opinion what header is the best to hold the
trace_printk.h to be included.
