Subject: tracing: Make ftrace_trace_stack() static
X-Git-Tag: v5.15~14704^2~65
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=ca475e831fd59e131bccd60de43c4104d82d02f5;p=platform%2Fkernel%2Flinux-starfive.git

tracing: Make ftrace_trace_stack() static

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