From 1d6288914264a22c0efdfb3a5748c101c0d12baa Mon Sep 17 00:00:00 2001 From: Wang ShaoBo Date: Thu, 21 Oct 2021 11:52:25 +0800 Subject: tracing/hwlat: Make some internal symbols static The sparse tool complains as follows: kernel/trace/trace_hwlat.c:82:27: warning: symbol 'hwlat_single_cpu_data' was not declared. Should it be static? kernel/trace/trace_hwlat.c:83:1: warning: symbol '__pcpu_scope_hwlat_per_cpu_data' was not declared. Should it be static? This symbol is not used outside of trace_hwlat.c, so this commit marks it static.
