In the function-graph tracer, add a funcgraph_tail option to print the function name on all } lines, not just functions whose first line is no longer in the trace buffer. If a function calls other traced functions, its total time appears on its } line. This change allows grep to be used to determine the function for which the line corresponds. Update Documentation/trace/ftrace.txt to describe this new option.
