From 0f24f1287a86b198c1e4bd4ce45e8565e40ff804 Mon Sep 17 00:00:00 2001 From: Li Zefan Date: Fri, 11 Dec 2009 15:45:30 +0800 Subject: tracing, slab: Define kmem_cache_alloc_notrace ifdef CONFIG_TRACING Define kmem_trace_alloc_{,node}_notrace() if CONFIG_TRACING is enabled, otherwise perf-kmem will show wrong stats ifndef CONFIG_KMEM_TRACE, because a kmalloc() memory allocation may be traced by both trace_kmalloc() and trace_kmem_cache_alloc().
