tracing: Add trace_printk sample code Add sample code to test trace_printk(). The trace_printk() functions should never be used in production code. This makes testing it a bit more difficult. Having a sample module that can test use cases of trace_printk() can help out. Currently it just tests trace_printk() where it will be converted into: trace_bputs() trace_puts() trace_bprintk() as well as staying as the normal _trace_printk(). It also tests its use in interrupt context as that will test the auxilery buffers.
