From f3f741019595f1e73564d985f5fe8abcbb98c769 Mon Sep 17 00:00:00 2001 From: Ezequiel Garcia Date: Sat, 8 Sep 2012 17:47:53 -0300 Subject: mm, slob: Add support for kmalloc_track_caller() Currently slob falls back to regular kmalloc for this case. With this patch kmalloc_track_caller() is correctly implemented, thus tracing the specified caller. This is important to trace accurately allocations performed by krealloc, kstrdup, kmemdup, etc. Signed-off-by: Ezequiel Garcia Signed-off-by: Pekka Enberg --- include/linux/slab.h | 6 ++++-- 1 file changed, 4 insertions(+), 2 deletions(-) (limited to 'include/linux/slab.h') diff --git a/include/linux/slab.h b/include/linux/slab.h index 0dd2dfa..83d1a14 100644 --- a/include/linux/slab.h +++ b/include/linux/slab.h @@ -321,7 +321,8 @@ static inline void *kmem_cache_alloc_node(struct kmem_cache *cachep, * request comes from. */ #if defined(CONFIG_DEBUG_SLAB) || defined(CONFIG_SLUB) || \ - (defined(CONFIG_SLAB) && defined(CONFIG_TRACING)) + (defined(CONFIG_SLAB) && defined(CONFIG_TRACING)) || \ + (defined(CONFIG_SLOB) && defined(CONFIG_TRACING)) extern void *__kmalloc_track_caller(size_t, gfp_t, unsigned long); #define kmalloc_track_caller(size, flags) \ __kmalloc_track_caller(size, flags, _RET_IP_) @@ -340,7 +341,8 @@ extern void *__kmalloc_track_caller(size_t, gfp_t, unsigned long); * allocation request comes from. */ #if defined(CONFIG_DEBUG_SLAB) || defined(CONFIG_SLUB) || \ - (defined(CONFIG_SLAB) && defined(CONFIG_TRACING)) + (defined(CONFIG_SLAB) && defined(CONFIG_TRACING)) || \ + (defined(CONFIG_SLOB) && defined(CONFIG_TRACING)) extern void *__kmalloc_node_track_caller(size_t, gfp_t, int, unsigned long); #define kmalloc_node_track_caller(size, flags, node) \ __kmalloc_node_track_caller(size, flags, node, \ -- cgit v1.1
