Date: Tue, 21 Oct 2014 14:19:29 +0200 From: Thierry Reding <thierry.reding@...il.com> To: Catalin Marinas <catalin.marinas@....com> Cc: linux-mm@...ck.org, linux-kernel@...r.kernel.org Subject: [PATCH] mm/kmemleak: Do not skip stack frames From: Thierry Reding <treding@...dia.com> Trying to chase down memory leaks is much easier when the complete stack trace is available. Signed-off-by: Thierry Reding <treding@...dia.com> --- It seems like this was initially set to 1 when merged in commit 3c7b4e6b8be4 (kmemleak: Add the base support) and later increased to 2 in commit fd6789675ebf (kmemleak: Save the stack trace for early allocations). Perhaps there was a reason to skip the first few frames, but I've certainly found it difficult to find leaks when the stack trace doesn't point at the proper location. --- mm/kmemleak.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/mm/kmemleak.c b/mm/kmemleak.c index 3cda50c1e394..55d9ad0f40d4 100644 --- a/mm/kmemleak.c +++ b/mm/kmemleak.c @@ -503,7 +503,7 @@ static int __save_stack_trace(unsigned long *trace) stack_trace.max_entries = MAX_TRACE; stack_trace.nr_entries = 0; stack_trace.entries = trace; - stack_trace.skip = 2; + stack_trace.skip = 0; save_stack_trace(&stack_trace); return stack_trace.nr_entries; -- 2.1.2 -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
