    tracing: Add trace_printk sample code · aad108aa
    Steven Rostedt (Red Hat) authored
    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.
