[QUESTION] check for mem in slab

[Cyrill Gorcunov]

Hi list,

in file mm/slab.c and routine kmem_cache_init() I found there
is no checking for allocated memory on line:

	/* 4) Replace the bootstrap head arrays */
	{
		struct array_cache *ptr;

		ptr = kmalloc(sizeof(struct arraycache_init), GFP_KERNEL);

--> no check for ptr == NULL <--

		local_irq_disable();
		BUG_ON(cpu_cache_get(&cache_cache) != &initarray_cache.cache);
		memcpy(ptr, cpu_cache_get(&cache_cache),
		       sizeof(struct arraycache_init));

		...

is that OK? or it's a bug?
