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.
