HI,
mm/slub.c: line 3973
int __kmem_cache_shrink(struct kmem_cache *s)
{
int node;
int i;
struct kmem_cache_node *n;
struct page *page;
struct page *t;
struct list_head discard;
struct list_head promote[SHRINK_PROMOTE_MAX];
unsigned long flags;
int ret = 0;
flush_all(s);
for_each_kmem_cache_node(s, node, n) {
How uninitialized variable node is being used in macro for_each_kmem_cache_node?
node is a local variable with no extern and not initialized.
mm/slab.h: line 490
#define for_each_kmem_cache_node(__s, __node, __n) \
for (__node = 0; __node < nr_node_ids; __node++) \
if ((__n = get_node(__s, __node)))
As we see for loop is based on node.
Thanks in advance.
Regards,
Amit Kumar
