Steven Rostedt (VMware) 4ee7c60de8 init, tracing: Add initcall trace events ... Being able to trace the start and stop of initcalls is useful to see where the timings are an issue. There is already an "initcall_debug" parameter, but that can cause a large overhead itself, as the printing of the information may take longer than the initcall functions. Adding in a start and finish trace event around the initcall functions, as well as a trace event that records the level of the initcalls, one can get a much finer measurement of the times and interactions of the initcalls themselves, as trace events are much lighter than printk()s.
