ftrace: warning in kernel/trace/ftrace.c
this warning: kernel/trace/ftrace.c:189: warning: ‘frozen_record_count’ defined but not used triggers because frozen_record_count is only used in the KCONFIG_MARKERS case. Move the variable it there. Alas, this frozen-record facility seems to have little use. The frozen_record_count variable is not used by anything, nor the flags. So this section might need a bit of dead-code-removal care as well. Signed-off-by: Ingo Molnar <mingo@elte.hu>
