How about more updates ?
Hmm, by grep (mmotm)
==
static struct page *get_partial(struct kmem_cache *s, gfp_t flags, int node)
{
struct page *page;
int searchnode = (node == -1) ? numa_node_id() : node;
==
==
static inline int node_match(struct kmem_cache_cpu *c, int node)
{
#ifdef CONFIG_NUMA
if (node != -1 && c->node != node)
return 0;
#endif
return 1;
}
==
==
debug:
if (!alloc_debug_processing(s, c->page, object, addr))
goto another_slab;
c->page->inuse++;
c->page->freelist = get_freepointer(s, object);
c->node = -1;
goto unlock_out;
}

Thanks,
