The function trace_printk_init_buffers() is used to expand tha trace_printk buffers when trace_printk() is used within the kernel or in modules. On kernel boot up, it holds off from starting the sched switch cmdline recorder, but will start it immediately when it is added by a module. Currently it uses a trick to see if the global_trace buffer has been allocated or not to know if it was called by module load or not. But this is more of a hack, and can not be used when this code is moved out of trace.c. Instead simply look at the system_state and if it is running then it is know that it could only be called by module load.
