X-Git-Tag: firefly_0821_release~176^2~700^2~65
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=ca475e831fd59e131bccd60de43c4104d82d02f5;p=firefly-linux-kernel-4.4.55.git

tracing: Make ftrace_trace_stack() static

ftrace_trace_stack() is not called outside of trace.c. Make it a static
function.
