From 4fd2735881bf4d8bf5e30979f31fc2f1b1d505fa Mon Sep 17 00:00:00 2001 From: Hannes Eder Date: Tue, 10 Feb 2009 19:44:12 +0100 Subject: [PATCH] tracing: fix sparse warnings: make symbols static Impact: make global variables and a global function static The function '__trace_userstack' does not seem to have a caller, so it is commented out. Fix this sparse warnings: kernel/trace/trace.c:82:5: warning: symbol 'tracing_disabled' was not declared. Should it be static? kernel/trace/trace.c:600:10: warning: symbol 'trace_record_cmdline_disabled' was not declared. Should it be static? kernel/trace/trace.c:957:6: warning: symbol '__trace_userstack' was not declared. Should it be static? kernel/trace/trace.c:1694:5: warning: symbol 'tracing_release' was not declared. Should it be static?
