From 73874005cd8800440be4299bd095387fff4b90ac Mon Sep 17 00:00:00 2001 From: Frederic Weisbecker Date: Wed, 3 Jun 2009 01:43:38 +0200 Subject: [PATCH] hw-breakpoints: fix undeclared ksym_tracer_mutex MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit 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 Signed-off-by: Frederic Weisbecker --- kernel/trace/trace_ksym.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/kernel/trace/trace_ksym.c b/kernel/trace/trace_ksym.c index 11c74f6404c..eef97e7c8db 100644 --- a/kernel/trace/trace_ksym.c +++ b/kernel/trace/trace_ksym.c @@ -44,12 +44,12 @@ static unsigned int ksym_tracing_enabled; static HLIST_HEAD(ksym_filter_head); +static DEFINE_MUTEX(ksym_tracer_mutex); + #ifdef CONFIG_PROFILE_KSYM_TRACER #define MAX_UL_INT 0xffffffff -static DEFINE_MUTEX(ksym_tracer_mutex); - void ksym_collect_stats(unsigned long hbp_hit_addr) { struct hlist_node *node; -- 2.39.5
