Mark functions as static in kernel/trace/trace_functions_graph.c because
they are not used outside this file.
This eliminates the following warning in
kernel/trace/trace_functions_graph.c:
kernel/trace/trace_functions_graph.c:333:5: warning: no previous prototype for
‘trace_graph_thresh_entry’ [-Wmissing-prototypes]
kernel/trace/trace_functions_graph.c:422:6: warning: no previous prototype for
‘trace_graph_thresh_return’ [-Wmissing-prototypes]
kernel/trace/trace_functions_graph.c:1408:6: warning: no previous prototype for
‘print_graph_headers’ [-Wmissing-prototypes]
