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.
