    Maybe I'm blind, but I don't see how kmem_cache_alloc can return NULL
    with __GFP_NOFAIL:
    - kmem_cache_alloc calls __cache_alloc.
    - cache_alloc only return 0 if cache_alloc_refill returns 0.
    - cache_alloc_refill only return 0 if cache_grow returns 0.
    - cache_grow only return 0 if
    * SLAB_NO_GROW is set in flags.
    * get_free_pages(flags) fails.
    * kmem_cache_alloc(flags&SLAB_LEVEL_MASK) fails.
    SLAB_LEVEL_MASK contains __GFP_NOFAIL.
