hw-breakpoints: fix undeclared ksym_tracer_mutex
ksym_tracer_mutex is declared inside an #ifdef CONFIG_PROFILE_KSYM_TRACER section. This makes it unavailable for the hardware breakpoint tracer if it is configured without the breakpoint profiler. This patch fixes the following build error: kernel/trace/trace_ksym.c: In function ‘ksym_trace_filter_read’: kernel/trace/trace_ksym.c:226: erreur: ‘ksym_tracer_mutex’ undeclared (first use in this function) kernel/trace/trace_ksym.c:226: erreur: (Each undeclared identifier is reported only once kernel/trace/trace_ksym.c:226: erreur: for each function it appears in.) kernel/trace/trace_ksym.c: In function ‘ksym_trace_filter_write’: kernel/trace/trace_ksym.c:273: erreur: ‘ksym_tracer_mutex’ undeclared (first use in this function) kernel/trace/trace_ksym.c: In function ‘ksym_trace_reset’: kernel/trace/trace_ksym.c:335: erreur: ‘ksym_tracer_mutex’ undeclared (first use in this function) make[1]: *** [kernel/trace/trace_ksym.o] Erreur 1 [ Impact: fix a build error ] Reported-by: Ingo Molnar <mingo@elte.hu> Signed-off-by: Frederic Weisbecker <fweisbec@gmail.com>
