    Subject[QUESTION] check for mem in slab
    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 <--

    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?
