For the system call payload documentation, you might want to refer to the Linux system call 
man pages. 

For internal kernel tracepoints like sched_switch, there is no documentation of the meaning of 
each field at the moment. This state is the same as the upstream Linux kernel trace event. You'll 
have to figure it out on your own. Documenting each field of the ~500-1000 Linux kernel tracepoints 
is no small task.
